in reply to Mixing up da Arrays (Golf)

Do I hear golf?

First at 48 chars, the one that modifies the original arguments like yours does:

sub Mix { my@a;@_=grep{@$_?push@a,shift@$_:0}@_ while@_;@a }
and a safe one that doesn't do that at 59 chars:
sub MixS { my@a;for(my$i;@_;++$i){@_=grep{$i<@$_&&push@a,$$_[$i]}@_}@a }
