Let's say you want to write a yacc grammar to parse Perl 6, or

hard in Perl 6. Certainly harder than it was in Perl 5.

I certainly hope not.
Quoting the delimiter is needed, by the way.
How is <<'END' disambiguated from <<'qw' list>>, anyway?

If your browser is using Gnome then holding down Ctrl+Shift while typing

As far as I understood, arrays and hashes, and references them are much
more similar in Perl6 than it was in Perl5.
F.e. we have @a and $a = [EMAIL PROTECTED];
the same:
push @a,1,2,3 push $a, 1,2,3
$b = @a $b = $a
(?) say "@a[]" say "$a[]"
(?) myfunc( [EMAIL PROTECTED
27 matches
