Bug Description
This is wrong:
(typep nil '(alien (* t))) => nil
especially given that the type translators accept NIL just fine -- translating it to NULL.
Secondly, it would be very convenient to be able to define an alien pointer type that excludes NIL / NULL. See bug 721087 for the special case of C-STRINGs.
