> 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.
