Neat. I think I would prefix the first 2 with something like ex-, to
avoid problems with definitions like:
(define 2.3 true)
(define 2 true)
In early versions of Smalltalk, it was actually possible to assign
True to the object 2, or vice versa, which caused all kinds of
interesting behavior. That isn't a problem any more, and it isn't in
DrScheme either.
