[Python-ideas] Re: SerialExecutor for concurrent.futures + Convenience constructor

The Dask distributed library has an API compatible with concurrent.futures, but would never be appropriate for inclusion in the standard library. It'd be perfect if Dask's Future objects would work well with concurrent.futures.as_completed. https://github.com/dask/distributed/issues/3695 has a view more details.
