There was some talk of it in the past, I don't know whether it's
definitely planned and/or when that would happen, but it seems part of a
general trend of protecting "constants." Perhaps an exception would be
made for True/False, but given the changes that are occurring here and
there, I'd program defensively around it. Best way for that is the
version test (ugly) or the physical test for the existence of the name
(elegant but swallows an exception).
