Whoops! We've fallen foul of Inform's rule saying that every room must

so although the game compiles successfully, it still causes an error to
be reported at run-time.
The best way round this is to extend the definition of our ``Room``

By doing this, we ensure that *every* room has a description of some
form; normally we'd override this default value with something
meaningful -- "The narrow street runs north towards the town square..."

You'll notice a couple of interesting points. Because we didn't supply
external names with our ``street`` , ``bow`` and ``quiver`` stubs, the
compiler has provided some for us -- ``(street)`` , ``(bow)`` and
``(quiver)`` -- simply by adding parentheses around the internal IDs
which we used. And, because our ``bow`` and ``quiver`` stubs have no
-``name`` properties, we can't actually refer to those objects when

finished game, but for testing purposes at this early stage -- they'll
do.

test compilation at this point, remove the previous set of stubs, and
instead add these -- ``south_square`` and ``apple`` objects, and a dummy
