Probably due to Tom's code, integration of functions with Heavisides in
them now works fine.

In https://github.com/sympy/sympy/pull/1376 it has been noticed that most
issues here are fixed, the remaining one is with .evalf()

There is another reference which might give quite some insight:

Feel free to implement something that lets you only do a subs in the main
part of the piecewise, though are you sure that that is ind

Yes, those wiki pages are where I would have referred you to. The best
thing to do would be to create an account on GitHub and then to fork the

I think you still need the other paper too because it talks about how to
convert a general piecewise function into a combination of Heaviside

Meh after going through the first paper I don't think it helps. It
requires the conversion of a piecewise function to the heavisid
