in thread Cant use array with numbers??

I like to put an explicit name in instead of $_, like so:

for my $value (@array) { do_something_with($value); }

Going back to the C/C++ style comparison, I also think $value is more readable than $array[$i], but that's a matter of opinion and/or of naming things well.

But remember that $value is not available outside the for loop. If you're worried about knowing where you are in the array, I've found I don't need to worry most of the time or I can just create put 'my $i = 0;' before the loop and do $i++ each time round.

How can you feel when you're made of steel? I am made of steel. I am the Robot Tourist.
