Of course, if you're making a fancy library, then the bells-and-whistles
version might contain a way to parameterize, so that it can "skip"
superfluos commas at the beginning and/or end. But that might be overkill.
Of course, the current behavior is probably related to why you can write
enum {
a,
b,
}
without a compiler error.
But you're right, in this case it may not be a sane behavior. And
definitely *not* what the programmer expects.
