Greetings!  I need a more powerful subtypep for the compiler, and it
appears I have one basically implemented.  I'd like to make use of the
second value to indicate whether the first type is in the complement
of the second type -- i.e. nil t means the types are disjoint (so that
the corresponding typep can return a constant nil), and I'd
like to return nil nil in cases of overlap even when I know the answer
for sure.  I think this should comply with the standard.  Please
correct me if wrong.  If this is the case, there are a number of tests
which insist on nil t and won't accept nil nil (like many others do),
e.g. (subtypep '(integer 0 10) '(integer 0 (10))).  Is this

Take care,
