To implement generic loop and set iterators, we are dependent on the following two things to work:

1. Need List wrappers to be supported for proper implementation of iterators:

T: TypeVar = TypeVar('T')
class ListIterator(Generic[T]):
    list: [T] = None
    index:int = 0
    def new(self: ListIterator, initVal: [T]) -> ListIterator:
        self.list = initVal
        return self
    def next(self: ListIterator) -> T:
        ret: T = None
        ret = self.list[self.index]
        self.index = self.index + 1
        return ret
    def hasnext(self: ListIterator) -> bool:
        return self.index<len(self.list)

def iter_list(lst: T) -> __ListIterator__:
	return __ListIterator__.new(lst)

2, Need T to support strings and lists so that we can support lists and sets of a wider variety.

Please check our forLoopsIterators-conflicts.md for more details.

Hi,

Currently, the class set doesn't have any fields, and neither does it support adding parameters or returning something from it's functions (class set is not included in the type checking environment). We tried changing those yesterday but the amount of changes required is a lot and we don't want to change how the sets group are implementing their functionalities.

Can the sets group support the above so that we can add next() and hasnext() in the set.wat file. Or can they implement next() and hasnext() as they proposed in their next milestone? To implement a set iterator, we need to be unblocked on this.

Thanks! @jpolitz @yalhessi @7bw
