Hi,

More specifically:

struct S{
    int[2] array;

    ref swizzle(string code)(){
             static if(code=="x") return array[0];
        else static if(code=="y") return array[1];
        else static assert("Unhandled");
    }
}

To make this work for const/immutable structs, I have to make 
another function with the header: auto swizzle(string code)() 
const{ copy or mixin the whole thing again... }

Maybe there is a language feature for this, like "auto ref" or 
"inout"?

Thank you!
