Proposed usage:

x = 5

with switch(x) as sw:

    if sw.case(4):
        assert False

    if sw.case(5):
        assert True
        sw.fallthrough()

    if sw.case(lambda x: x > 3):
        assert True

    if sw.case(6):
        assert False

    if sw.default():
        assert False

    Heh, I just dropped into this repo to make the exact same suggestion. 😄

    Could probably even shorten sw.case(4) to just case(4) (that is, naming the context variable case and making it callable). sw.default() could then be spelled case.default(), which is a bit charming. Ditto case.fallthrough().
