Is it just me or does it seem wrong that undef == 0 evaluates to true?

Update: In retrospect, I feel kind of stupid for having asked this question and wish I had just thought about it a little more (or at least asked in a less permanent way :). At the very least, though, it has reconfirmed for me the importance of use warnings and maybe next time I won't grumble at the "Use of uninitialized value in numeric eq".
