in the kit; it's the handler function, which we will define here. But in order
for the references in the kit to match up correctly, we must therefore make

The return statement isn't necessarily reached, because even if the firing
condition holds, the < span class = "extract" > < span class = "extract-syntax" > ...< / span > < / span > code may decide to return in some other way.

It provides only a default to cover rules which don't specify an outcome.
