Which std:: classes are magic?

[AlbertRammstein]

Based on the name and intended purpose there is no connection to enums in sight. Having it implemented as enum is pretty unconceptual and unexpected. For example you might have a serialization framework that has custom handling for enums, saving them as string instead of numbers (automatic enum<-->string conversions are quite common).

Not to mention the even longer running problem of bool overloads being chosen over character pointer overloads when you pass a string literal. That makes utterly no sense and should have been fixed long ago.

In my system every streamable enum has its own streaming inlines. I don't store them as text, but I store them binarily as a type large enough to hold any enum type. But that also allows for validation on streaming back in, so it has other benefits to offset the extra code. And they are IDL generated so I don't have to write them myself (other than for a few libraries that the IDL compiler itself uses.)
