I do not appreciate the BOOST_DEFINE_ macros for enumerations. We get as much as four of them, ...

We'll even get eight once the requested support for class-nested enums is added. :-)

and neither is able to handle the use case that I consider basic, which I often have in my code: where I omit value zero and start from 1:

struct Error { badSoething = 1, badSomethingElse, tooLongSomethng, ... };

So, I am not sure how many real life enums these macros cover.

They cover the common case of an enumeration without any initializers; the case where you have a number of alternatives but don't care about their exact numeric values. I do believe this is reasonably common, even if it's not universal. E.g. enum class Shape { Triangle, Rectangle, Circle }. Further e.g. template class evariant: public variant { public: E index() const { return (E)variant::index(); } }; and then evariant, and JSON serialization gives you ["Circle", {"radius": 14.2}]. Or perhaps {"Circle": {"radius": 14.2}}. :-)
