The short answer is "don't do that". C<my $v if 0;> has already been deprecated in the development version of Perl because its behavior is too confusing. The behavior cannot be changed because too many people rely on it. $ bleadperl -wle 'my $v if 0;' Deprecated use of my() in false conditional at -e line 1. -- Michael G Schwern [EMAIL PROTECTED] http://www.pobox.com/~schwern 'All anyone gets in a mirror is themselves,' she said.
