Well, one of the big problems with Perl 5's dereferencing is that it's
painful to create intermediate variables that make it any easier. For
example, you can say "my $ref = $x{$y}{$z};@$ref" or you can say "local
*ary=$x{$y}{$z};@ary" but the latter isn't that obvious to most, and can
run afoul of strict. In Perl 6:
my @ary := %x{$y}{$z};
should make it much more likely that we'll all use those intermediates.
I also seem to recall something about a ".@" operator that would work
like so:
for %x{$y}{$z}.@ -> $i {...}
No? If everything else is chained on the right for dereferencing, I
certainly see the utility in this. Am I imagining that it was stated
earlier?
What's more that could be:
for *%x{$y}{$z} -> $i {...}
and I can't imagine it makes any sense to bind that * anywhere but:
for *(%x{$y}{$z}) -> $i {...}
I like the division between @ and *, since the two meanings had somewhat
too much overlap in most code.
