How to map elements of a tuple?

[Andrey]

Hello,
Is there a template/function/mixin... in the library that I can 
use to map elements of a tuple?

> object.foo(Mapper!myMapFunction(1, bool, "Qwerty", 
> EnumedColor.Red));

where "Mapper" is this mapper and "myMapFunction" is a template 
function that I want to apply to each member in tuple.

I know that there is std.algorithm.map but as I understand it is 
suitable only for arrays (types are the same).
