    In Common-Lisp, I think you use (declare (special VAR
...)) to indicate
    a localized use of dynamic binding (as the first thing
inside the let
    form where it is bound).

    Since Elisp already uses `declare' for some other
things, it would seem
    reasonable to also use it to inform the byte compiler
that an apparently
    local variable is known to be accessed non-locally.

I would not mind adding this feature to Emacs Lisp.
But I still think that part of Gnus should get a total
rewrite
using a different mechanism.
