Perl 6 Rules
Perl 6 rules are the regular expression, string matching and general-purpose parsing facility of Perl 6, and are a core part of the language. Since Perl's pattern-matching constructs have exceeded the capabilities of formal regular expressions for some time, Perl 6 documentation refers to them exclusively as regexes, distancing the term from the formal definition. Perl 6 provides a superset of Perl 5 features with respect to regexes, folding them into a larger framework called rules, which provide the capabilities of a parsing expression grammar, as well as acting as a closure with respect to their lexical scope. Rules are introduced with the rule keyword, which has a usage quite similar to subroutine definitions. Anonymous rules can be introduced with the regex (or rx) keyword, or simply be used inline as regexes were in Perl 5 via the m (matching) or s (substitution) operators.

Service Loose Coupling Principle
Within the service-orientation design paradigm, service loose coupling is a design principle that is applied to the services in order to ensure that the service contract is not tightly coupled to the service consumers and to the underlying service logic and implementation. This results in service contracts that could be freely evolved without affecting either the service consumers or the service implementation.

Religious Studies
Religious studies, alternately known as the study of religion, is an academic field devoted to research into religious beliefs, behaviors, and institutions. It describes, compares, interprets, and explains religion, emphasizing systematic, historically based, and cross-cultural perspectives. While theology attempts to understand the nature of transcendent or supernatural forces (such as deities), religious studies tries to study religious behavior and belief from outside any particular religious viewpoint. Religious studies draws upon multiple disciplines and their methodologies including anthropology, sociology, psychology, philosophy, and history of religion. Religious studies originated in the 19th century, when scholarly and historical analysis of the Bible had flourished, and Hindu and Buddhist texts were first being translated into European languages. Early influential scholars included Friedrich Max Müller, in England, and Cornelius P. Tiele, in the Netherlands. Today religious studies is practiced by scholars worldwide. In its early years, it was known as Comparative Religion or the Science of Religion and, in the USA, there are those who today also know the field as the History of religion (associated with methodological traditions traced to the University of Chicago in general, and in particular Mircea Eliade, from the late 1950s through to the late 1980s). The term "religion" originated from the Latin noun "religio", that was nominalized from one of three verbs: "relegere" (to turn to constantly/observe conscientiously); "religare" (to bind oneself [back]); and "reeligere" (to choose again). Because of these three different potential meanings, an etymological analysis alone does not resolve the ambiguity of defining religion, since each verb points to a different understanding of what religion is. During the Medieval Period, the term "religious" was used as a noun to describe someone who had joined a monastic order (a "religious"). The religious studies scholar Walter Capps described the purpose of the discipline as to provide "training and practice... in directing and conducting inquiry regarding the subject of religion". At the same time, Capps stated that its other purpose was to use "prescribed modes and techniques of inquiry to make the subject of religion intelligible." Religious studies scholar Robert A. Segal characterised the discipline as "a subject matter" that is "open to many approaches", and thus it "does not require either a distinctive method or a distinctive explanation to be worthy of disciplinary status." Different scholars operating in the field have different interests and intentions; some for instance seek to defend religion, while others seek to explain it away, and others wish to use religion as an example with which to prove a theory of their own. Some scholars of religious studies are interested in primarily studying the religion to which they belong. Scholars of religion have argued that a study of the subject is useful for individuals because it will provide them with knowledge that is pertinent in inter-personal and professional contexts within an increasingly globalised world. It has also been argued that studying religion is useful in appreciating and understanding sectarian tensions and religious violence.

Bayonetta
Bayonetta is an action hack and slash video game developed by PlatinumGames and published by Sega. The game was originally released for Xbox 360 and PlayStation 3 in Japan in October 2009, and in North America and Europe in January 2010. The game was later released on the Wii U alongside its sequel, Bayonetta 2, releasing in September 2014 in Japan and worldwide the following month - the two games were later released worldwide on the Nintendo Switch in February 2018. An enhanced port for Windows was released in April 2017 with 4K support. A remastered version of Bayonetta as well as another PlatinumGames title, Vanquish, was released for PlayStation 4 and Xbox One on February 18, 2020, as part of a compilation to celebrate the 10th anniversary of the game. Bayonetta takes place in Vigrid, a fictional city in Europe. The game stars the eponymous character, a witch who is capable of shapeshifting and using various firearms. She possesses magical attacks, and she can use her hair to summon demons to dispatch her foes. It features a rating system, which gives players a grade based on their performance, and a combat system that is similar to the Devil May Cry series. Development of the game was started in January 2007, with Hideki Kamiya being the game's director. According to Kamiya, the game was completely original, though he drew some inspirations from Scandinavian mythology, and played Devil May Cry 4 for reference. The game's theme is "sexiness" and "partial nudity", and that the characters were designed to be "fashionable". Kamiya and artist Mari Shimazaki spent more than a year to create Bayonetta's design. Several demos were released for the game prior to its launch. Bayonetta was the third project released by PlatinumGames, which was founded by former Clover Studio employees. Upon release, the game received generally positive reviews. The game was praised for its combat, presentation and soundtrack, but drew criticism for its story and quick time events. Bayonetta was nominated for and won several end-of-the-year accolades, and had sold over a million units worldwide by 2010. An anime film adaptation of the game by Gonzo, titled Bayonetta: Bloody Fate, was released in Japan in November 2013. A third game, Bayonetta 3, is in development for the Switch.
