I don't know why you are being so hostile, but I see little point in continuing.

Yes, I had a thinko and switched A and B once. BFD. As for the rest run the following code and observe the scoping carefully:

for (my $foo) {
  $_ = "In scope";
  print "Inside: $foo\n";
}
print "Outside: $foo\n";

If you can get Perl 5.003 and run the same code. Note the differences.

This change is no larger than it would be to see the inline for loop scoped exactly like a regular for loop. That change would ruin merlyn's snippet. Therefore, knowing about this past change, I raised my concern over whether this specific scoping detail was likely to be safe across releases of Perl. merlyn said point blank that it was a risk, but thought it didn't matter much since so much will change in Perl 6.

I don't think I have any more to say on this topic. You wanted to know why I asked the question. You have your answer. No matter how stupid you think the question was, both merlyn and danger gave me reason to think that it was not unreasonable...
