Forwarding arguments through a std.algorithm.map

[Nordlöw via Digitalmars-d-learn]

If I have a function

    bool f(Rs...)(Rs rs)
is it somehow possible to map and forward all its arguments `rs` 
to another function

    bool g(Rs...)(Rs rs);

through a call to some map-and-forward-like-function `forwardMap` 
in something like

    bool f(Rs...)(Rs rs)
    {
        alias someArbitraryFun = _ => _;
        return g(forwardMap!(someArbitraryFun)(rs));
    }

?

What should the definition of forwardMap look like?

Does Phobos contain something like this already?
