C++, match custom placeholders with function arguments

I am trying to write the piece of code which will do the following: let's assume we have a call of custom bind function

auto bind_obj = bind(some_func, _1)  

and after we have

auto res = bind_obj(42, "test") 

where the function some_func:

int some_func(int val, string test)

How can it possible to match placeholders with arguments provided in actual function call, i.e. bind_obj(...)??

In other words, is it possible to iterate over std::tuple (arguments and placeholders here) and variadic pack (function arguments) to:

1. deduce the return type of function some_func;
2. make correct std::tuple to further use it in some_func() call ?

I am trying to do this via pure C++, not boost nor std::functional. I think, my main problem is that i don't understand how to build tuple at runtime with arguments (where all the placeholders replaced correctly) and to deduce return type.

I saw _Mu template structure in STL "functional.h" but it looks too complex and overloaded.
