Imho that's to much magic and way to special, and as errors often are regular
enums themselves, we'd end up in two levels of them.
There has been a discussion about ad-hoc enums before, but those were supposed
to be used as parameters (which seems lot less complicated to me — but still
wasn't simple enough to be added to the language).
