I think it sounds really good, but shouldn't it really be

  V = FunctionSpace(mesh, finite_element, dof_map)

So

  dofmapset --> dof_map
  form --> finite_element

Yes, it should be implemented there.

ok. Could you put it on the todo list? Either we can keep editing the
TODO file in DOLFIN, or we can have a TODO list on the wiki. I think
Garth suggested this yesterday.
