Do you mean that the scoping_type maps the "native enum" type of the (emulated) scoped enum back to the (emulated) scoped enum? I.e., native_type and scoping_type are inverse metafunctions?
Yes.
Then all I can suggest as a better name is *maybe* scoped_type or scoped_enum_type. But scoping_type might be fine.
Hmm, scoping_type and scoped_enum_type seems reasonable, but I prefer yet the use of native_type. What do others think?
Beman has created his scoped enum emulation just for this purpose, but it lacks some scoped enum features as it is implicitly convertible to the underlying type.
How is it otherwise different from your implementation? Does it use simpler syntax or fewer (meta-)functions?
Extracted from the file boost/detail/scoped_enum_emulation.hpp: // Caution: only the syntax is emulated; the semantics are not emulated and // the syntax emulation doesn't include being able to specify the underlying // representation type. // // The emulation is via struct rather than namespace to allow use within classes. // Thanks to Andrey Semashev for pointing that out. // // Helpful comments and suggestions were also made by Kjell Elster, Phil Endecott, // Joel Falcou, Mathias Gaunard, Felipe Magno de Almeida, Matt Calabrese, Vincente // Botet, and Daniel James. // // Sample usage: // // BOOST_SCOPED_ENUM_START(algae) { green, red, cyan }; BOOST_SCOPED_ENUM_END // ... // BOOST_SCOPED_ENUM(algae) sample( algae::red ); // void foo( BOOST_SCOPED_ENUM(algae) color ); // ... // sample = algae::green; // foo( algae::cyan ); and here the emulation code # define BOOST_SCOPED_ENUM_START(name) struct name { enum enum_type # define BOOST_SCOPED_ENUM_END }; # define BOOST_SCOPED_ENUM(name) name::enum_type The syntax is similar, but the used type is BOOST_SCOPED_ENUM(name) for Beman design and name in mine.
