Re: Iterating over verbatim hash reference

See Re: Why is "for" much slower than "while"?: by using for instead of while you don't create the hash again in each loop.

I thought about using `for`, but how do I loop in this way over a hash, so that the key-value association is maintained? Of course I could do something like `for ([qw(key1 val1)],[qw(key2 val2)],....) { my $key=$_->[0]; my $val=$_->[1]; ... }` [download] but this too is not quite a response to my original problem, which is, looping over a hash. Or maybe I misunderstood you? Could you give some example? -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

for

for ([qw(key1 val1)],[qw(key2 val2)],....) {
  my $key=$_->[0];
  my $val=$_->[1];
  ...
}
