As has already been pointed out in this thread, Emacs does have (via
cl-lib or more specifically cl-macs) a version of `declare' whose
special-variable declarations are respected by the byte compiler.  So
it's a solved problem; I don't understand why Pascal and others are
NIHing it and then complaining about the deficiencies of Emacs Lisp.

The general usefulness of this functionality, however, does make me
wonder why it's still stuck in the cl namespace.  It seems like a prime
candidate for promotion to subr or similar.
