template
void for_each_argument(F f, Args&&… args) {
using arrT = int[];
static_cast(arrT{ (f(std::forward(args)), 0)… });
}

How should we factorize non-static methods of a class? If it were usersManager.findUser(), would the final call always be a global function like findUserFinal() which wraps instance of UserManager?

Also, wrapping all these functions should be done during app initialization in wiring up stage and there should be some service/factory to provide all factorized functions? Otherwise, the code would become polluted with all the repeated wrapping calls, right?

I am new to C++ and have a problem compiling your example with Visual Studio 2017. The for_each_argument function (see below) creates an compiler error: C4576 ‘a parenthesized type followed by an initializer list is a non-standard explicit type conversion syntax’.

Any idea how to fix this?

Thanks for your help!
