Depends. The issue is that since `assert` is stripped out in “O” mode, if the codebase depends on `assert` for correctness… they’re not compatible.

What do you mean by depends on assert for correctness? How?

    get_president_inside_bunker()
    assert president_is_inside_bunker()
    close_bunker_doors()
    assert bunker_doors_are_closed()
    send_nukes()

With asserts enabled this is fine. With asserts disabled you might start sending nukes while the president is still outside or the doors to the bunker are still open.

Thanks! I never thought anybody would do such a thing.

No one should, but it happens.
