Ack.
I'm of two minds whether that "__is_constant()" macro should be
explained or not.
A small voice in my head says "that wants a comment".
But a bigger voice disagrees.
It is a work of art, and maybe the best documentation is just the
name. It does what it says it does.
Art shouldn't be explained. It should be appreciated.
Nobody sane really should care about how it works, and if somebody
cares it is "left as an exercise to the reader".
