Review Comment:
Let's do explicit type ignore at callsite. The `Any -> Any` case basically
breaks other checks. All the iterator cases fall into the `Any` case and we
lose track of the actual data type. Let's throw away any `Any`, use `type:
ignore[type-abstract]` to ignore that warning. We will still have a lot of
information (the return type from the function for example).
