“enum class” emulation or solid alternative for MSVC 10.0

Question

I\'m looking for a hacky kind of solution to the following problem: GCC 4.4+ accepts the following c++0x code:

enum class my_enum
{
    value1,
    value2
};

Do not use this solution. See the accepted answer by Howard for a better solution. I'm leaving this post here because Howard's answer refers to it.

If you need to be able to compile your code with a compiler that doesn't yet support a new, not yet standard or not yet widely implemented language feature, it's best to avoid using that language feature in your code.

That said, as a hack workaround, you can wrap the enum in a struct and use a pair of implicit conversions:

struct my_enum {
    enum type { 
        value1, 
        value2 
    };

    my_enum(type v) : value_(v) { }

    operator type() const { return value_; }

private:

    type value_;
};
