Now I propose another form to round out the "binding" family
MACROEXPAND-FLET. Use it to define functions that are only used
during the dynamic extent of macroexpansion.
MACROEXPAND-LET* would be icing on the cake because the same effect
could be achieved by using a series of nested MACROEXPAND-LETs.
macroexpand time binding of a macro (dynamic scoping),
COMPILER-LET (or MACROEXPAND-LET, if you prefer) is of very marginal
benefit, if any. If people feel that such a thing must be fully rounded
out for reasons of symmetry, I say we should flush the whole thing.
I also feel that it was a major mistake letting MACROLET in, but I've
already lost that battle twice and don't plan to fight it again.
