Yes, I'm just about to.

Yes, we can assume that the Form constructor takes a vector of
FunctionSpace pointers (or shared pointers). The generated code will
add the appropriate constructors:

  class Form
  {
    Form(Array<FunctionSpace*> function_spaces);
    Form(Array<std::tr1::shared_ptr<FunctionSpace> > function_spaces);
  };

  class PoissonBilinearForm : public Form
  {
    PoissonBilinearForm(FunctionSpace& V0, FunctionSpace& V1);
    PoissonBilinearForm(std::tr1::shared_ptr<FunctionSpace> V0, std::tr1::shared_ptr<FunctionSpace>);

    PoissonBilinearForm(Array<FunctionSpace*> function_spaces);
    PoissonBilinearForm(Array<std::tr1::shared_ptr<FunctionSpace> > function_spaces);
  };
