It would be easy to add a bunch of extra calls for 4, 5, 6,
etc. arguments but I think we should avoid using varargs for this (it
might also work only for built-in types).

How about just calling solve() for one Function and then picking the
components manually, that's what happens in VariationalProblem for
multiple Function arguments:

  Function u;
  solve(u);

  u0 = u[0];
  u1 = u[1];
  u2 = u[2];
