    Looking at the code, yeah, same object can be added twice to the
    ToManyList. While I am still leaning in favor of leaving things as
    they are now, I can see how this can cause problems if you add and
    then remove the same object.

    Any possible solution would require a list to behave like a Set on
    add or at least on remove. This adds overhead.
