Do you mean `frozendict(d)` where d is frozendict? If so, you don't need to create a new dict. You can just incref the d and return it. That is what we do in tuple and frozenset. > I think the major speedup is due the fact I implemented the solution with a > split dict, as suggested by Inada.

In general, combined dict is little faster and much efficient. -- Inada Naoki <songofaca...@gmail.com> -- https://mail.python.org/mailman/listinfo/python-list
