Parameters

Name	Type	Description
stack	deque	A double-ended queue containing iterables to be processed, used to manage the traversal of nested data structures.
seen	Optional[Set]	A set of object memory addresses used to track visited objects and prevent infinite recursion in circular references.
maxlevels	int	The maximum depth of nested objects to traverse before truncating the output with an ellipsis.
level	int	The current nesting depth level during the recursive traversal.
isinstance	Callable	The function used for type checking, typically the built-in isinstance.

Returns

Type	Description
Iterator[Any]	An iterator yielding pairs of tokens (strings or literal markers) and the current iterable being processed.
