The idea is that the equations solver and the optimization package will have very similar code base and API (much like now, but the link will be strengthened even more).

I hope the Base package makes the API non-package specific. There are some good nonlinear solvers outside of this crew (Kinsol from Sundials is one, Roots.jl is another). It would be great for library code to finally have swap-ability between them, a la
