This isn't about catching bugs in the program, it's about validating user input. That's a common enough task that it deserves to have a convenient way to do it correctly.

+1. An enum is basically a bidirectional mapping between some raw values and some "nice" instances, so it deserves a well-defined lookup operation in each direction.
