Hi all,
I notice this failure in master (this is without hash randomization):
./bin/test --no-subprocess sets

It is fixed by this patch:
diff --git a/sympy/core/tests/test_sets.py b/sympy/core/tests/test_sets.py
> index adaba2d..4ce6051 100644

But I am not sure if this is the proper way to fix it, as one could argue
that set(Intersection(...)) should return a set that includes python types
instead of sympy types.
Cheers,
