You realize, I hope, that there is no end of different "special non-value"
semantics. Perl had one, now you're proposing a second. RDBMS gurus
have as many as 29. One step down that path is a bad precedent.
undef is sufficient. Let there be operators for implementing the various
semantics, NOT new special non-value values.
