Pattern Matching

The following examples present pattern matching using the match keyword for the catch-all case.

Encouraged

The _ is used for the catch-all to indicate the important cases have been defined above and the last case is not important enough to warrant a name.

Alternative

We may apply an appropriate name to provide context to the reader; however, unless it provides additional information the preferred usage is defined in the encouraged case.
