Forwarding arguments through a std.algorithm.map

[Nordlöw]

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?
