And you've made debugging tricky by not providing code that clearly replicates your issue - neither Foo nor Bar are ever called or referenced, your global $gVar is never assigned a value and the flow of your program is unclear. Please read I know what I mean. Why don't you?.

Based on your comments, it looks like you expect to assign $gVar a value as a loop index and then maintain that value when Bar is called within the loop. However, when you use $gVar as the index on your foreach, you actually create a lexically scoped copy (or rather a local alias for the list element). When you then call Bar, it only sees the global. It's discussed (briefly) in Foreach Loops. Perhaps this example will provide clear flow: 

my $var = 5;
foreach $var (1 .. 3) {
    print $var;
    print_var();
}
print $var;
sub print_var {print $var};
