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.
