I agree.  I think we should eliminate all binding of symbol function
definitions.  The way to start would be to make `letf' give a warning
for attempts to bind symbol function definitions.

Indeed, maybe we should discourage let-binding of anything except
symbols' values.  Perhaps `letf' is simply a bad idea.  It looks like
that was added for the sake of completeness.,

Can anyone suggest a case for which `letf' is a good method?
