New submission from Nathaniel Manista nathaniel@google.com:
So I'm fixing a bug in typeshed's accounting of the traceback module (https://github.com/python/typeshed/pull/2436) and the documented semantics of traceback.format_list don't quite smell to me what I think they might be intended to be:
1) I know it has the name "format_list", but is it really intended to require a list? Why not a sequence, or a collection, or an iterable? I would think it would be fine to pass an iterable to traceback.format_list. Is it fine?
2) What is the desired component type for the aggregate passed to format_list? In 3.4-and-earlier it was Tuple[str, int, str, Optional[str]], and that still works in 3.5-through-3.8, but is that just backwards compatibility or is that something that users of traceback.format_list should feel encouraged to continue passing into the future?
Sorry for filing a bug just to ask "huh; really?" but... please confirm?
