IntIterators are not Iterable

[kaug-whis]

using Lambda;
...
(1...3).iter(i->trace(i));

The above seems like it should be valid syntax, but since IntIterator does not have an iterator():Iterator<Int> method to allow it to work as an Iterable, it does not work.

The real problem here is that Lambda works with Iterable, not Iterator. That's where this issue should be addressed, but I don't know how exactly to do that.

Making Lambda work with both would be relatively simple, for example using an abstract with implicit conversions from both Iterable and Iterator: https://try.haxe.org/#8e6b3e3d

Huh, I thought we disallowed the combination of static extensions and implicit casts, but I guess I'm thinking of something else.

Right, it doesn't work with [0,1,2].iter(item -> trace(item));

And this looks silly 😅

overload extern inline function iter<T>(it:Iterable<T>, fn:T->Void) {
	for (item in it)
		fn(item);
}

overload extern inline function iter<T>(it:Iterator<T>, fn:T->Void) {
	for (item in it)
		fn(item);
}
