I definitely avoid $$hRef{key} and $$aRef[0] (using $hRef->{key} instead). But I don't really like @{...} much (too hard to match up the open and close braces) so I prefer @$aRef and %$hRef to the versions with {}. For @{$aRefs{key}} I have no choice.

But when (and if) a version of Perl comes out with "the patch" applied, I'll be switching to nearly exclusively using -> to deference. This patch allows $aRef->@, $hRef->%, $aRef->@[1..5], etc. which are particularly nice for cases like $aRefs->{key}->[0]->getList()->@[2..6].
