I am not sure what is lacking in VS2012, but there is some way to overcome this problem.

template struct FunctorParameterType { static auto init() -> typename decltype(&T::operator()) { typedef typename decltype(&T::operator()) func_type; return func_type(); } typedef typename decltype(FunctorParameterType::init()) func_type; typedef boost::function_types::parameter_types parameter_types;

typedef typename boost::mpl::at_c::type type; };
