yes, that's not the point.  the point is the difference
between undef and '' and '0' and 0 is important.  if someone
doesn't know why the two loops are not identical, then I'd
be wary of their understanding of Perl booleans in general.
there are way too many cargo-cult programmers out there.

yes, I'm being pedantic.  there's a normal tension between
programming as mathematics and programming as engineering.
this is not going to go away anytime soon.
