Yes indeed. When I was re-writing the main.cpp file for this demo I noticed that
it was easy to get confused about which FunctionSpace to use.

E.g., for u and v I could use one of the following:
PoissonBilinearFormArgumentSpace0
PoissonBilinearFormArgumentSpace1
PoissonLinearFormArgumentSpace0
PoissonLinearFormCoefficientSpace0
PoissonTestSpace
PoissonTrialSpace

and still get the same result. For forms with many functions this only gets
worse. A nice feature would be if one could do:

PoissonFunctionSpace v("v");
PoissonFunctionSpace u("u");
PoissonFunctionSpace n("n");
PoissonFunctionSpace h("h");

or something similar, to be sure that the function space was picked correctly.
