Enumerations 🆕

An enumeration (an enum) is a type whose values are a fixed set of named constants — the days of the week, the colours of a traffic light, the suits in a deck of cards. Instead of remembering that 0 means red and 1 means amber, you give each value a name and let Raku keep track of the numbers.

This section shows how to define an enum and how to move between its names and the values behind them.
