   When \var{o} is non-\NULL, returns a type object corresponding to
   the object type of object \var{o}. On failure, raises
   \exception{SystemError} and returns \NULL.  This is equivalent to

   This function increments the reference count of the return value.
   There's really no reason to use this function instead of the
   common expression \code{\var{o}->ob_type}, which returns a pointer
