Hi Oliver,

No, it doesn't and I can not do it with the current macros. With the PP-SEQ
and the variadic macros I could generate something allowing print a textual
representation for the enum as the Enum library in the Vault does,

std::cout << c_str(ae) << "\n"; // could prints out 'green'

but I'm sure this will be begin of long list of requests, locales
adaptations, input from a string representation, ... I would prefer to
concentrate on a pure scoped enum classes emulation for the first release of
the library.

Best,
Vicente
