<p class="commentary">The "test head" is the "if" line here, and the "test tail" is the "}". The
return statement isn't necessarily reached, because even if the firing
condition holds, the "..." code may decide to return in some other way.
It provides only a default to cover rules which don't specify an outcome.

<p class="commentary">In general the test is more elaborate than a single "if", though not very
much.
