Why am I not surprised to see you trolling HN too? What's all too sweet is that you've brought your anti-Go zealotry here too! Joy.

> Except Google Go returns several values instead of tuples, so you can't just collect all the results as-is.

This is false. Functions in Go do not have to return multiple values. Therefore, you can "collect all the results as-is".

> And with no generics it would be annoying to actually use e and the result, since they would need casts. Too bad.

Actually, it wouldn't be annoying, because you wouldn't use a general purpose map like you've shown. You'd use code shown in the parent.

If you think you can do asyncMap in Google Go, without casts and without manually collecting multiple return values, by all means show us the code. I would find that really interesting.

I didn't claim I could. Take your trolling elsewhere.
