I'm working on enhancing Perl6::Subs[*] to support more parameter
traits than just C. I have some questions about
parameters and traits. (These questions all apply to pure Perl 6,
which I know I won't be able to translate completely, but I want to
know which target I'm missing.)

Would this be a good time to ask for explanation for C being
never Unicode, while C is always Unicode, thus leading to an
inability to box a non-Unicode string?
And might I also ask why in Perl 6 (if not Parrot) there seems to be
no type support for strings with known encodings which are not subse

You know, Java did one thing in this respect that I liked, and managed
to do it in a way that I couldn't stand. The idea of program as object

That's not quite it. C is a forced Unicode level of "Bytes", with
encoding "raw", which happens to not have any

I'd say that $0 is a specialization of $/, but yes, basically, they
both represent the current match result, albeit di

How can you have a level independent position?
The matching itself happens at a specified level. (No
