This is also one of the ways to go forward. I personally dislike it because:
- A non trivial amount of functionality needs reimplementation (flatten for instance) - We do not have "standard correct way" to interface with functions like factor, symplify, had, get, atoms, etc, so it is hard to be sure that you have implemented everything - As a personal preference, I actually like "garbage in - garbage out" But this way has been proven to work in matrix expressions and is also used in Pernici's tensor module, so I am not against it. -- You received this message because you are subscribed to the Google Groups "sympy" group.
