While this is not yet a complete emulation of scoped enums, it has the advantage of that there is no need to use a macro to name the strong type.
I don't know if it will be confusing to put provide both approaches in a single mini library.

Out of curiosity, what are the cons of this implementation compared to the existing one? (The pros seem fairly obvious, but I think I'm missing the downside...)
Respect to the Beman approach, the major downside I can see is that a strong enum is not always and enumeration, so cannot be used in a portable way where an enum is expected (e.g. switch, ...). Something else is needed to be able to write portable code. In addition, not all c++ compilers provide explicit conversion, so either we need to use a explicit function to convert to the underlying type or let the underlying type conversion operator implicit.
