Please don't do it, it does not help ANYTHING.
This is just one minor way people can shoot themselves in a foot, but
compared to what you can do with, say, "fset" it's just a joke.
The original proposal was to make t and nil constant, with the thought
that this will provide some roadmap for being able to make a lot of
symbols constant, and that would have a real life speed benefit for
speeding up GC.
But not being able to unintern t and nil is not useful to anyone.
