Re: Which Perl?
I thought Perl was just a wrapper to add functionality to regex, because you can't quite write a program just with a regex.
I'd not realised that Perl6 wasn't just a later version of Perl5. I've written one Perl program and I'd no idea what version. So I checked:
perl -v
This is perl 5, version 22, subversion 1 (v5.22.1) built for x86_64-linux-gnu-thread-multi
(with 73 registered patches, see perl -V for more detail)

So the only issue is a new name for Perl6?
