Yeah, it might be scoping. Easy enough to test. Just do:
{
use warnings;
}
print "uninit ", $a, "\n";
And indeed, no warning. Guess you have to use if.pm. I wish it had a
less ridiculous version number. I guarantee someone will balk at
installing it because "the version number is too low" or something dumb
like that. At least it comes with 5.8.0.
