This is an interesting subpage under Cobra- http://cobra-language.com/docs/quality/
it actually bears a little on recent discussions about self-documenting code. I'm a Perl6 beginner so I'm making comments with expectation that others will correct where I'm wrong * Doc Strings Perl6's vision of "doc strings" are more powerful than what are in Cobra * Unit Tests Cobra's language-level test constructs looks cleaner then Perl's culture-level tests. * Contracts Hmmm, those look like a cross between assertions and unit tests... not sure how they fit in Perl6 * Compile-time Nil Tracking Sounds like strong-typing to me, which one can easily request in Perl6 * Assertions Pretty sure Perl6 has'em
