Language feature to apply function to each element of a parameter pack

Question

Does anyone know, if there exists a standards proposal for a c++ language feature that would allow me to replace this (thanks to Yakk):

template<class... ARGS>
void bar(const ARGS& ... args) {        
    auto t = { (foo(args),0)... };
    (void) t; //<- prevent warning about unused variable
}

with something more natural like this:

template<class... ARGS>
void bar(const ARGS& ... args) {        
    foo(args)...;
}

foo being e.g. a function, a function template and/or an overloaded set of those, whose return type might be void (or in general which I don't care about).

Btw, if someone knows a more concise way to write this in c++14, feel free to share, but I think, this is already handled in this question

Answer 1

Use a fold expression with the comma operator:

( void(foo(args)) , ...);

I didn't see any proposal to change this further in recent mailings.
