Indeed, your comment was exactly the source of my comment (BTW, thank
you, this helped me to fix my Python wrappers)

In general, I think MPI standard should be fixed/clarified in many
places regarding to handling of returned references. Testing for
predefined Comm a Group handling is rather easy, but for Datatypes is
really cumbersome. Perhaps a MPI_Type_is_named(MPI_Datatype, int*flag)
would help a lot. What do you think?
