Sure, but an empty string is not the same as a FALSE if I am storing
both and considering them distinct.  I know about ===.  But I want to
get exactly what I store back from memcached, if I store an '' or a
FALSE then I should get exactly a '' or a FALSE in return and when I
test with === it should match up.

With returning a single value and no error code indication this is
simply not possible as whatever the sentinel that indicates a miss is
can now not be stored and retrieved reliably.  This is clearly a rare
situation, but I think it's important to support.
