Description (last modified by jdemeyer)

For a SymPy option to solve (#22322) we need to translate any assumptions on variables (and maybe anon. functions?) that were made using assume and var('x', domain=...). Any SymPy operation may access the SymPy knowledge base any time. So I think this should be handled the same way as with Maxima, i.e. at the time the assume/var calls are made.

For the converse, see #24334

However see ​https://trac.sagemath.org/ticket/22322#comment:12 So the database is idle play?

For variables, couldn't this be handled in the conversion Sage -> Sympy?

Yes, SympyConverter:symbol().
