which was merged three weeks ago and which touched sage.sets.real_set.py.
My current bet is that this ticket somehow forces
`sage.sets.cartesian_product` to be loaded upon Sage's startup. Hence,
when running `load_submodules(sage.sets)` it does not appear anymore
as the first entry, and instead the output starts with the next one
which turns out to be `sage.sets.real_set`.
If that's confirmed, a good approach would be to make sure that all
the affine Weyl group code is lazy imported. That's a good property to
have anyway.
Cheers,
Nicolas
