The enum is in the scope of the union, so you should be able to do

  u = M.U(M.A, foo)

where foo is the right type for case A.

I believe ORBit-Python fails to cope with the nested enum. See my
mailing list posting:

Here, the enum is in the scope of S, so you should be able to do

  s = M.S(M.S.B)

Again, it seems to be broken with ORBit-Python.
