Actually, it rather annoyed me to find it in all caps. I typed into the
program with initial caps for a reason. If it's not something that goes
out to a user, why worry about it? For most my enumeration printing in
C, a couple nested "?:" did the trick.

How does this help you understand the code?

Yes, if you added a default case at the end of the switch statement. The
array is a totally different issue - a valid point to complain about.

If it is just something I toss into a program and don't care how it
looks or runs, just that it does, that's what I call a quick'n'dirty
hack. YMMV

No, it just means that a C enum is not quite the same abstraction as an
Ada enum.
