I did not follow the discussion on the new function system that Jens seems to be building, but what would be ideal is if the user could implement "jump" by deriving from "step" and simply add the automatic simplification jump^2 -> jump
Anyway it is not difficult to cut&past the entire definition of step to user's code, rename and make few desirable alterations. -- Vladimir V. Kisil email: kisilv@maths.leeds.ac.uk -- www: http://maths.leeds.ac.uk/~kisilv/
