> Notice how the discussion is full of edge-cases which this code doesn't handle? Can you point to a single unhandled edge case mentioned so far in this discussion? The only possible one I see is finnh's complaint that it doesn't support changing arguments, but that seems more like a missing feature (which doesn't seem that important to me) than an edge case. The logic needed to correctly implement this is quite minimal, and implementing it yourself both spares you a rather heavy dependency and gives you more flexibility.
