-The preceding code declares a discriminated union Shape, which can have values of any of three cases: Rectangle, Circle, and Prism. Each case has a different set of fields. The Rectangle case has two named fields, both of type `float`, that have the names width and length. The Circle case has just one named field, radius. The Prism case has three fields, two of which are named Unnamed fields are referred to as anonymous fields.
