-<p>
- The case expression is the most common kind of flow control in Gleam code. It
- is similar to <code>switch</code> in some other languages, but more powerful
- than most.
-</p>
-<p>
- It allows the programmer to say "if the data has this shape then run this
- code", a process called <em>pattern matching</em>.
-</p>
-<p>
- Gleam performs <em>exhaustiveness checking</em> to ensure that the patterns in
- a case expression cover all possible values. With this you can have confidence
- that your logic is up-to-date for the design of the data you are working with.
-</p>
-<p>
- Try commenting out patterns or adding new redundant ones, and see what
- problems the compiler reports.
