taking Infinity or dropping 0

[michaelficarra]

Should iter.take(Infinity) or iter.drop(0) return iter instead of wrapping it unnecessarily?

I would lean towards wrapping, for consistency. It's weird for the identity to depend on the precise value of an argument like this, and I can imagine code along the lines of

let next = Iterator.HelperPrototype.next;
[...]
let skipped = base.drop(n);
[...]
next.call(skipped);

which would break if it happened to hit one of the special cases.

Not totally convinced on this one, but I will admit it's unusual. Closing.
