If we did that, we'd be replaying $path from the beginning every time
the user said something that didn't match the grammar.  For a podcast
episode like a radio show, that's bad—you don't want to be 30 seconds
or two minutes into the content and have to start over.

Also, as I said, it's always matching one of the rules in our
grammar--even if I literally say "goobledegook."  So it's unclear how
we'd implement $response_good.
