Hi, I have this code
from sympy import * i = Idx('i') A = Indexed('A', i) A.free_symbols for a in A.free_symbols: print(type(a)) It seems that the behavior has changed. With a previous version of SymPy, all the types are Symbol which is what I expected. But in the master branch, the type of Idx in free_symbols are Idx and not Symbol. Is it an issue ?
