I'd love is_subtype if it weren't for the fact that my idea of
subtyping has considerably broadened since I started doing generic
programming.  There were also people who like is_base_and_derived
because it made the order of the arguments perfectly clear.  If you
imagine currying is_subtype<D><B> it almost seems like it should tell
you whether B is a subtype of D.
