There are two Rust things I'd really like to dive into next: - Understanding how to and then writing a `concurrent_map(limit, closure)` adaptor, and - understanding how it works and then contributing to rust-analyzer

Would this be different than map from rayon?

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)
