Oh, I have another one of those for you.  The result of an expression
like (1 == 0) is another strangly magic value.  It behaves like
undef insofar as counting as a string of length 0 in string context
(""), but as a proper 0 when used numerically.  Yet unlike undef,
it elicits no complaints from using the -w flag.
