Hi everyone. Tom has this commit in his gsoc-2 branch https://github.com/ness01/sympy/commit/43877ee46e6b4095e2667df4636c3a14b4b820d1. In it, he defines Tuple().is_Atom to be True, i.e., the empty Tuple.
Is this problematic, since isinstance(Tuple(), Atom) would still be False? Apparently some code relies on objects that cannot be traversed further through .args to have is_Atom == True. Is this a reasonable assumption for that code to make? And if the answers to these questions are yes, then can it be setup through some kind of metaclass logic to make Tuple() an instance of Atom but not Tuple(1), for example?
