OK you're way behind - there's a complete new version/reorganisation since
then, however you're quite right, we use that methodology already for
is_class.

How about this:  are functions implicitly convertible to void*, I *think*
they are but haven't checked yet, a function would then be a type that is
implicitly convertible to void* (but not a user defined conversion), but is
not a pointer or array.  Does this make sence?
