Re^2: Iterating over verbatim hash reference

This doesn't answer my question, because you are introducing a variable for the hash ref here, i.e. $h. Of course this works, as you see from the 2nd example in my original posting. The point is to do it without naming the hash/hashref.

... without introducing a new* variable ...* The following variation doesn't introduce a new variable because `$_` already exists! (I believe the following is also Stupid Hash Trick #58.) `>perl -wMstrict -le "for ({ qw(a 1 b 2 c 3) }) { while (my ($k, $v) = each %$_) { print qq{$k => $v}; } } " c => 3 a => 1 b => 2` [download]	[reply] [d/l] [select]

It isn't possible, you need a name.	[reply]
