Then, to get the correct const semantics:
const Wrapper<const Foo> w(myConstFooReference);
Ugly, but it works.
Critiques?
Well, the unfortunate thing is that it doesn't determine the const-ness of Wrapper automatically. You'd like
Wrapper<const Foo> w(myConstFooRef)not to compile, I presume. I'm not sure how to achieve this with normal constructor semantics, though.
