I propose EXPR->@ for @{EXPR}.
So that would be $x{ $fred->{Blah} }->@[1..3]
Note that $$fred{Blah} can currently be written as $fred->{Blah}, and
look a lot better IMHO.
Another example (since this is what I thought the above did at first):
@{$x->{${$fred{Blah}}}}[1..3]
(with spaces)
@{ $x->{ ${$fred{Blah}} } }[1..3]
becomes
$x->{ $fred{Blah}->$ }->@[1..3]
(without spaces)
$x->{$fred{Blah}->$}->@[1..3]
It's still not pretty, but at least you can read it left to right.
"Take x, dereference and look up something in its referenced hash. What
something? Well, lookup Blah in the %fred hash and dereference it to get
a scalar. Now take the result of that %$x lookup and grab elements 1..3
out of the array it references."
