Re: foreach count variable

Okay, many are going to flame me, but this looks like an excellent occasion to use a C-type loop:

for (my $count = 0; $count < scalar(@bar); $count++) {
  printf "%d -> %s\n", ($count, $bar[$count]);
}

You needn't flinch, there's nothing wrong with that. An alternative is: `my @foo = qw(one two three four); for (0..$#foo) { print "$_ : $foo[$_] \n"; }` [download] Andy.	[reply] [d/l]

yeah, thats the other way doing it. but still too much keys to press, and it looks quite 'untidy' :-)	[reply]

Your idea is fine, but the execution could be better.. :) There's no need for scalar nor printf there. `for (my $count = 0; $count < @bar; $count++) { print "$count -> $bar[$count]\n"; }` [download] But then, I'd still prefer the `for(0 .. $#bar)` form proposed further down the thread.
