Code Review

This pull request relaxes type checks in check_string_list and check_number_list from list to Iterable (excluding str and dict) to support other iterable types like tuples and sets, with corresponding test updates. The reviewer noted that using Iterable allows generators or iterators, which can be exhausted during validation and will raise a TypeError when len() is called. The reviewer suggested using Collection instead of Iterable to ensure the input is sized and can be safely iterated multiple times.
