In the FFC-produced wrapper code for DOLFIN, could will still generate a
Form constructor which takes the coefficient functions (or a vector of

with a pointer to a form. Doing
Form* a;
a = new WeightedPoissonBilinearForm(V, V);
it's not possible to attach coefficient functions because a Form doesn't
know about them, only WeightedPoissonBilinearForm does.

Is this something that happens in user code (so it needs to look
nice)?
Otherwise, just do
Form* a;
static_cast<WeightedPoissonBilinearForm*>(a)->f = f;
In this case, how and when do you set the FunctionSpace of the form?
I don't see a problem in having the old constructor of the type
PoissonLinearForm(dolfin::FunctionSpace& V0, dolfin::Function& v0)
existing alongside the new approach such that the user can avoid doing too much
complicated stuff.
