missing functionallity?

Rob,

How do you revert one of the optimize-interface qualities to NIL?  I added
a (declaim (optimize-interface ...)) to one file, but the effects carried
over into the next file.  But I couldn't figure out how to revert it back.
Shouldn't there be some way to do this?

Even if you change compile-file and load to bind the cookies, you still
need some way to do this because people (well, me at least) quite often
type in optimizer declaimations at top level.
