I prefer &$thingy over $thingy->(). It's one character less (three less if you're not passing arguments), and it's more general. This works:
&{ Block returning a code reference }
but this doesn't:
{ Block returning a code reference }->();

That's why I also prefer:

$$hash_ref{key} = $$array_ref[1];
over
$hash_ref->{key} = $array_ref->[1];
-> is not a shortcut. It's a detour ;-)
