Hello everybody and happy new year I was thinking to RFC the following union:
``` typedef IterableFactory = array | IteratorAggregate; ``` As you know, passing Iterators around is a bad idea because one can accidentally end up using them concurrently. For example if one entity is traversing the iterator, and a second entity calls rewind() and fully traverses the very same iterator, the first entity would try to continue the traversal from a finished iterator. So in order to avoid this kind of confusing designs we generally keep iterators as confined as possible - instead, we pass around "iterator factories" such as `IteratorAggregate`. However, that doesn't include arrays, which can be safely iterated concurrently as well. Hence my proposal. Essentially this is like `Iterable` but excludes `Iterator`. Thoughts? TY
