Don't be mislead by that name. Although Perl6::Form was a prototype for something that was planned for Perl 6, Forms/formats aren't part of the language specification anymore (and to be handled by libraries instead).

AFAIKnew Forms/formats have never been part of the language specification and always been intended to be handled by libraries instead - but libraries that would be in core Perl 6, thus I don't think I've been mislead by the name: Perl6::Form still is by all means the prototype implementation of Perl 6's Form.pm.
