Okay, I know that this is a really easy one, but it's been bothering me. I've looked at all kinds of docs, but I can't seem to find an answer to this. I'm sure I'm looking right past the answer, and not seeing it.

How do I scope a variable so it can only be seen in the 'main' section? I _thought_ that 'my' was supposed to handle this but I guess not in the way I was thinking.

Exmple code:

#!/usr/bin/perl -w

use strict;

sub foo();

my $bar = "I can see you";

&foo;

sub foo()
{
    print "inside foo:  $bar\n";
    return(0);
}
