It seems to me that it would make even more sense to actually bind the
variable's global value despite any dynamic bindings; this certainly would
be unusual, but even warning about it violates the the usual `let' binding
semantics.

(If this were judged to be a good idea, one could even have
`set[q]-global' that would provide the capacity in general.  Of course, on
that note one could have `makunbound-global' and even `makunbound-default'
to complete the possibilities...)

Of course, there would then be no way to fool a `defvar' if you wanted 
the global variable left unbound, but that seems like an unlikely desire 
(and there's always `makunbound' if you're desperate).

This is all admittedly somewhat insane, so if it's rubbish, here's a 
message idea:

"Can't bind `foo-bar' globally: `let' around `defvar'"
