Still not working optimally:
   
    mesh = UnitSquare(1, 1)
    V = FunctionSpace(mesh, "CG", 1)
    Q = FunctionSpace(mesh, "CG", 1)
    M = V + Q
    print "V.num_sub_spaces() = ", V.num_sub_spaces()
    print "M.sub(0).num_sub_spaces() = ", M.sub(0).num_sub_spaces()

   
gives:

    V.num_sub_spaces() =  1
    M(0).num_sub_spaces() =
    Traceback (most recent call last):
      File "form_manipulation.py", line 108, in <module>
        print "M.sub(0).num_sub_spaces() = ", M.sub(0).num_sub_spaces()
      File
    "/home/meg/local/lib64/python2.6/site-packages/dolfin/functionspace.py",

        return self._dolfin_element.num_sub_elements()
