// The delicious_snacks module is trying to present an external
|
|
// interface (the `fruit` and `veggie` constants) that is different than
|
|
// its internal structure (the `fruits` and `veggies` modules and
|
|
// associated constants). It's almost there except for one keyword missing for
|
|
// each constant.
