[...] I managed defining a specific opaque type, let me say MyGreek, and defining implicit conversions from these types.
Your example could be written as
std::cout << string(MyGreek(1)) << std::endl; std::cout << string(MyGreek(6)) << std::endl; std::cout << MyGreek(Alpha) << std::endl; std::cout << MyGreek::Alpha << std::endl; // using nested literal std::cout << string(MyGreek(Alpha)) << std::endl; std::cout << string(MyGreek::Alpha) << std::endl; // using nested literal std::cout << MyGreek(17) << std::endl;
If think this interface corresponds more to how C++ conversions work (IMO of course).
(Or does boost even offer something like that already?) I don't think so. The closest could be TBoost.Enums in the sandbox, but this library generates the enum and don't do the mapping.
I think that it can do both plain enums and enums that map to arbitrary types. Here is an example where string are associated with enum values:
Hi,
The link correspond to Boost.Enum, I was talking about TBoost.Enums (https://svn.boost.org/svn/boost/sandbox/enums/libs/enums/doc/html/index.html).
Best, Vicente

I am sooo looking forward to using C++11 :-) Currently I am working with explicit conversion functions. I am aiming for the implicit version suggested by you once I can use class enums. Regards, Roland
