Utility function which can be used to implement a naive, slow, but
thorough chunk scan for automatons.
This method is designed to be directly useable on automaton classes to
provide the `scan()` interface.
This function depends on implementation details of ``Chunk``.

Utility function which provides a chunk scanner which only examines the
