Yes! Will revise the patch accordingly and use Just's suggested name, fromseq(). Do you prefer the default value to be None or True? Earlier discussions on python-dev showed that True is more meaningful to some in the context of membership testing. OTOH, dict.setvalue and dict.get both use None.

I think it should be None -- let's be explicit when we want True.
