Yep, this is bad IMHO.  Your concern is valid I think, but your
"solution" isn't a good one.  Why not just use a module like Damian's
Quantum::Superpositions?  (i.e. create a Null object that propigates
the unknowability of the value through operations)  If it's part of
the standard distribution, then those that want null in perl can have
it and we don't have to live with Yet Another Keyword.
