would like Promise.flatMap to exist

Which... Isn't helpful at all to your original tweet now that I've read it again, since `Promise.all(promises).then(Array.prototype.flat)` is a thing, and having those be more generic isn't remotely helpful for what you asked for
I guess with the generic versions you can write a more generic version of exactly what you asked for

I'm just curious about how much these monad container switches generalise -- I'm not sure why they need to be traversable compared to just supporting the notion of flatten/concat that one needs for >>=
-
It's actually the other way around (sorry, I know I implied otherwise earlier -- I'm not a Haskell expert). Traversable is adjacent to Monad. e.g. you can go `HashMap<K, Future<V>>` to `Future<HashMap<K, V>>`, but not the other way around.
