Perl 6 "is a highly capable, feature-rich programming language made for at least the next hundred years."
Among the features that advance the tradition of expressive and feature-rich programming of the Perl family of programming languages, Perl 6 provides object-oriented programming including generics, roles and multiple dispatch, functional programming primitives, definable grammars for pattern matching and generalized string processing, optional and gradual typing, and a long so on.
