Also, after trying to sketch an hyperelasticity solver in C++ dolfin
with the new function design, I'm considering generating typedefs
to FunctionSpace subclasses using function names like

FooForm::FunctionSpace_u, FooForm::FunctionSpace_Q,
FooForm::FunctionSpace_dt etc.

as well as using actual form names from the .ufl file for the
dolfin::Form subclass name:

%(prefix)sForm_%(uflformname)s

examples:

ElasticityForm_f
ElasticityForm_F
ElasticityForm_J
ElasticityForm_J_adjoint
ElasticityForm_J_action
...

ElasticityForm_f::FunctionSpace_u V(mesh);
Function u(V);

since a .ufl file should be able to contain many forms to reuse things
like element and function definitions, and stuff like material laws in
both equations and postprocessing forms etc.
