   2) FUNC pseudo: is TRUE iff the return type of the function is a pointer
      to a type whose name differs from that of the function only in that
      the function name begins with a lowercase letter and the type name
       begins w/ an uppercase name.

The region & filter code has lots of pseudo constructors that don't
use this convention (e.g. openFilter, allIntegers, etc.) When do we
need to know if a function is a pseudo constructor? Since most of them
are, we could just use a tag to indicate non-pseudo-constructors.
