When you loop over a list, the local variable is aliased to each member of the list.

Yes, I got that part. The part that surprises me is that B::Deparse deparses it to something that doesn't work, and I always assumed that the deparsing was correct. Consider:

use strict;
use warnings;
foreach $_ (my ($foo, $bar, $baz)) {
  $_ = "default";
}
print "$foo\n";

This code doesn't run, and it is what I mistakenly assumed your code was the equivalent of (minus the use's and print).
