Do you mean wrapping sage.symbolic.e
If the differential forms are somewhat immutable we may also save the
result of is_zero once for all. Why do not make is_zero a cached_method of
symbolic expressions ?

Hi Dox,
In addition to the link that Leif provided, it would be good to open a
ticket on trac first with a description of the changes you propose to make.
Let me know if you need any further help. I'd be happy to review your patch
when you're done.
All the best,
Joris

I think most time is spend in the is_zero() method for a symbolic
expression, and that the reassignments you refer to are largely irrelevant.
The thing is that it can cost a lot of time to decide whether, for example
sin(x)cos(x) - sin(2x)/2
is equal to zero, because there is so many things to
