From working perspective, perl5 is good enough to me, but from glue perspective, perl5 is not good.

For example, It seems to me Inline, XS and embed Macro are not derived from pure perl5 culture. they are more like some hacking on working around.

perl6 surly get rid of many shortcoming of perl5. but I'm interested to see how rakudo handle that problem. If it can link other languages resources(perl5, C, python etc) easily, I don't care when pure perl6 package become mature.
