I want to point out that, technically, using Deref for this is an anti-pattern, as Deref is intended exclusively for smart pointers. Nothing really wrong with doing this outside of some loss in opacity (and unexpected behaviour if you're writing a library), but it's worth pointing out

Note that that language has changed:

I don't really see the issue in providing Deref for a wrapper type like this. Could you elaborate? I'm not trying to gain full encapsulation, just trying to make sure I'm passing the right kind of wrapper, then using it transparently.
