My apologies for the rather careless wording of my earlier message.

What I wanted to say was: if SET! extends the "global" environment,
then that environment has become special in that it is the ONLY
environment that can be extended by interactive definition.  This
would seem to preclude the existence of many such environments.

DEFINE eliminates the problem, because it specifies, very precisely,
the environment in which the name is bound.
