If it's in geometry, then it might work, since this syntax of assume was created at the beginning for Xcas interactive geometry, to be able to make proofs while displaying something.

Quote:I understand your point. I don't know whether applications like the geometry app implicitly rely on CAS evaluation. If this is the case, then there sure will be side effects. Otherwise I still am of mind that this should be feasible.

I don't think it's that simple, because the whole system is built with the idea that arguments are eval-ed. As for the apps, geometry is a CAS app, the others apps are independant of the CAS.
