perl -we may be more informative - perl sees the undefined value, and 
casts it to zero - okay, I see your point.  Hmmm.  If you check for 
defined $x, $x is undef, but if you check for ==0, it warns, then makes 
it equal zero anyway.  DWIM gone too far?

Oh well.  Show me a perfect computer language...
