Might be helpful.

Well, in my tree i moved some of the multimethod-declarations (getitem/setitem) for
the dictobject into some dict-specific descriptors. I could reuse the existing
methods without any modification. It's faster and easier to understand.
But i see your point that in other cases the declarativeness of
multimethods is nice. But I do think that their existence complicates
the understanding of PyPy (at least for me :-).
