The verbosity is what makes it fail the "truly elegant"
test for me. And I would say that it does violate DRY
in the sense that you have to write value() repeatedly
for no good reason.

Sure, it's not bad enough to make it unusable, but like
all the other solutions, it leaves me feeling vaguely
annoyed that there isn't a better way.

And it *is* bad enough to make writing an enum definition
into a dreary chore, rather than the pleasure it should be.
