Sometimes, when iterating over a tuple representation of a class or struct, I
want to modify the class/struct contents.  Ex:

struct S {
    uint foo = 1;
}

void main() {
    S s;
    foreach(element; s.tupleof)
        element = 2;
    writeln(s.foo); //Still prints 1
}

It would be nice if I could do something like:

foreach(ref element; s.tupleof)

and this would modify s.foo.
