If I put EXCLUSION in the type_func_name keyword list, it works fine.
But I'm having a little trouble trying to use EXCLUDING or EXCLUSIVE,
because if I move them from unreserved to any other keyword list, I get
reduce/reduce conflicts.

Am I doing something wrong? I would assume that making words more
reserved would usually not lead to conflicts.
