IMHO it makes sense to rename it to match its concept and hence making it
easier to learn (discover) for people that know the concept from other
languages:
- Clojure: core.match (https://github.com/clojure/core.match)
- Scala: match keyword
(http://docs.scala-lang.org/tutorials/tour/pattern-matching.html)
- Racket: match form (http://docs.racket-lang.org/guide/match.html)
- F#: match expression (https://msdn.microsoft.com/en-us/library/dd547125.aspx)
