i've read that scoped template specalization is allowed in C++17 - is it
planned for the next gcc release?
otherwise i will switch to an if constexpr solution - but would be still
to have this feature
checked compiler:
gcc trunk (and latest intel) do not support it
clang (starting with release 7) and MSVC (starting with VS2017(i don't
know the exact revision)) supports it
------
enum class E{ A };
struct Ta{ int x; };
struct Mapper
{
template<typename Type> struct type_to_enum{};
template<> // <-- FAILS
struct type_to_enum<Ta>
{
static constexpr auto value = E::A;
};
};
