Thank you! Rebindable does exactly what I need.

I'm just curious why there is no some syntax to describe the same.
E.g.
    const(Foo) foo; // mutable ref to const object
    const Foo foo;  // const ref to const object

Using of const is inconvenient w/o mutable refs.
I understand that Rebindable doesn't add overhead, but it looks a 
bit ugly.
