I don't particularly like __locallookup__ either, but haven't found a better name yet.  "__lookup_in_class__" was the best alternative I could come up with, and that feels different than other special methods.  The name in the PEP is more or less derived from _PyType_Lookup, with "local" meaning "only in this class, don't recurse in the rest of the MRO".
