That could be problematic, because if Perl 6 sees something like:
my %myhash; %myhash{'foo'} = 'bar';
It's going to think 'ahah', perl 5'. Because it doesn't contain any Perl 6 keyword (such as 'module' or 'class'), as Mark said.
But then trying to process that as Perl 5 will result in an error. This doesn't seem particularly sane to me. Will we have to say
use 6;
on all Perl 6 programs to avoid this kind of thing?
Forgive me if I'm missing something obvious here.
The other question was "how do I label my code as Perl 6?" The correct answer, according to Apocalypse 1, is to start your source with "module" or "class".
Here is the relevant paragraph from the apocalypse: I hereby declare that a |package| declaration at the front of a file unambiguously indicates you are parsing Perl 5 code. If you want to write a Perl 6 module or class, it'll start with the keyword |module| or |class|. I don't know yet what the exact syntax of a module or a class declaration will be, but one thing I do know is that it'll set the current global namespace much like a |package| declaration does.
