--- Comment #19 from DB <db0451 at gmail dot com> --- just for anyone finding this later, note this has been raised at the level of the C++ Standard - http://wg21.link/p0375r0 - with the conclusion being: > EWG pointed out that most enumerations are exhaustive, and > we want to be annotating the exception, not the norm. > However, there wasn’t much appetite for a “non-exhaustive” > annotation, either; implementers were of the opinion that > current heuristics for diagnostics for switch statements > on enumerations are sufficient. - via https://botondballo.wordpress.com/2016/07/06/trip-report-c-standards-meeting-in-oulu-june-2016/ I suspect that "most enumerations are exhaustive" is an overgeneralisation that only holds for some people you could ask, but hey.
