There. There already are several ways to do cleanup on exit/return using
existing features, why add one more?

Not really. If, for some reason, I didn't know what's in that trap and were
super paranoiac about it, I could do

    oldaction=$(trap -P EXIT)
    trap 'eval "$oldaction"; bar' EXIT

I've never been in such a situation though.

Don't get me wrong, I just like it when new features align with the old
ones and work together nicely.
