This is a good idea, but with one caveat:
I've seen twice already bugs caused by people using ALL_CAPS counter
entries in enums, and then someone trying to use them in #if conditions,
where it resolves as `0` since the preprocessor doesn't know them.

I would strongly advise to use lower case names, so as to avoid this
confusion.
