Wrong code for MSVC

[andriish]

In some cases binder will generate code that is not compatible with MSVC, e.g.

using _binder_ret_0 = class std::map<std::string, std::string >;

The following code is will not compile in MSVC:

#include <stdexcept>
#include <string>
#include <map>
using _binder_ret_0 = class std::map<std::string, std::string >;
int main()
{
    _binder_ret_0 a;
    a["a"]="a";
    return 0;
}

but is OK for GCC.

To make the code compatible one should remove the "class" word.

using _binder_ret_0 = std::map<std::string, std::string >;
