declarations

[Earl A. Killian <EAK at MIT-MC>]

On the question of (declare (special x)) at top-level vs.
imbedded, perhaps the right thing to do is to leave the top-level
one named "special", and invent a new name for the imbedded one,
such as dynamic.  (declare (dynamic x)) at top-level would be
nop because it's non-pervasive like var declarations in general,
whereas (declare (special x)) would be prevasive as before.  Not
clear whether (declare (special x)) should be defined imbedded or
not.

The Maclisp unspecial doesn't exist; is this intentional?
