Okay, now that that's all cleared up, time to propose something.
When writing Perl 5, I always find myself writing @{ more often than @$.
Maybe it's just a bad habit that I don't tend to use a lot of
intermediate variables.
I propose that the precedence of the of the dereferencing sigils be
loosened so I don't have to write those pesky squigglies all the time.
What used to be:
for my $i (@{$foo->{bar}[$ind]}) { }
Can now be:
for @$foo{bar}[$ind] -> $i {...}
It doesn't feel quite right, but that's probably because I've written it
the other way so much.
The only reason to keep it around is if you wanted to use the archaic:
@$foo[2];
Or if you wanted to call methods on the array:
@$foo.sort;
But since you can call methods on a reference and get them delegated
anyway, that's not a problem. And as for the first one, well, who needs
that when they can just leave off the @ altogether?
