Runge-Kutta is for integrating functions that you know a formula for.
Afterthought--suppose you do have a formula that has some nasty integral that you can only compute numerically.
Put it into expr--then we could implement the RK4 method with messages and some patching.
Or maybe make some implementation with expr~, although it could be a bit more difficult. I guess it just depends on the application you want to create.
