#RocketLang update:I implemented some additional library functions, namely:- `dynamic_type(x)`: returns the actual runtime type of the object. E.g., if the variable x is declared as `SomeProtocol` but you assign an instance of a structure implementing that protocol, it will give you the structure type.- `is_subtype(T1, T2)` tests if T1 is a subtype of T2, similar to Python's `issubclass()`- `os.scandir()` for getting the contents of a directoryI also added a generic iterator that works with `ArrayList`s and array `Slice`s. All it needs is that the underlying container can be queried by `container[index]` and can be queried for its length.(I actually already had this implemented for ArrayLists, just made it more generic to make it work for Slices, too.)This actually required fixing a "bug" in checking whether a type implements a protocol. Implemented naively, that lead into an infinite recursion. (I was aware of that and had a FIXME in my code.) Now I accidentally triggered that and figured it was a good time to actually fix that.
