Yes, but that was not obvious from the tweet :) I want to have a way to speed up a slow map op (say, parse a file) by doing it in parallel and buffering its results, to then return *a regular iterator* and yield *in the original order* (yes, this is a very specific requirement)

Wait, does a rayon slice.par_iter().map(...) not return the elements in order?
