foo.hpp

template<typename T>
struct CastToNative {};

template<>
struct CastToNative<int> {
	int operator()(Local<Value> value){return value->ToInteger()->Value();}
};
template<>
struct CastToNative<char *> {
	char * operator()(Local<Value> value){return *v8::String::Utf8Value(value);}
};
template<>
struct CastToNative<const char *> {
	const char * operator()(Local<Value> value){return CastToNative<char *>()(value);}
};
template<>
struct CastToNative<double> {
	double operator()(Local<Value> value){return value->ToNumber()->Value();}
};
template<>
struct CastToNative<std::string> {
	std::string operator()(Local<Value> value){return std::string(CastToNative<char *>()(value));}
};

Is this the right/best way to unbox a type? other than maybe using a macro for DRY?
