I think pyrsistent uses the same data structure -- HAMT. Regardless of that, using it is a nonstarter because (a) we already use the bulk of frozenmap implementation to power the contextvars module; (b) pyrsistent is 15x slower, see https://gist.github.com/1st1/be5a1c10aceb0775d0406e879cf87344#gistcomment-3020936
