Re: Iterating over verbatim hash reference

for( my $h = { qw' x 5 y 8 ' }; my($r,$s)=each %$h; ){
  print " $r = $s \n";
}
__END__
 y = 8
 x = 5

You're the first person to call it verbatim hash in 10 years :) SPRINGLE

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. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

... 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]
