I ain't broke, but brother I'm badly bent
* module/ice-9/expand-support.scm (strip-expansion-structures): If, when producing @/@@ forms, we find that an @@ variable is not bound in its module, just serialize the symbol. This bends hygiene, in that it can introduce a global (but not lexical) reference in the expanded module, but it seems necessary to not produce (@@ (foo) else) in forms like ((@@ (foo) cond) ((test then) ((@@ (foo) else) bar))).
