Maybe the example below will clear things up for you. I don't
understand why you could use anon subs, since they're not a lot of
difference between "sub foo {}" and "$foo = sub {}" except the latter
doesn't have the problem you're running into.
sub main
{
my $test=shift;
test();
return $test;
sub test {
print "X=".$test."\n";
}
}
main(1);
main(2);
Output:
X=1
X=1
Have a nice day,
