A new experimental feature has made it into perl, Postfix Dereference Syntax. The idea appeared Postfix, whole-object dereference operators in 2000 .
It popped up a few months ago and made it into a perl release in october
And today ikegami updated Mini-Tutorial: Dereferencing Syntax and I learned of it
$r = \@a;
@b = $r->@*; # equivalent to @$r or @{ $r }
$r = [ 1, [ 2, 3 ], 4 ];
$r->[1]->@*; # equivalent to @{ $r->[1] }
