Objects that provide strong invariants are easier to work with, too, and I value a strong invariant far more than a default constructor. In fact, I almost never have any use for the latter.

Right. Never mind that--I don't know what I was thinking.

I'm not sure point b) is as absolutely true as you state it to be. I believe there are cases where you can provide such a nothrow move. The most obvious case is for objects that have no deep data.

Ok. I wasn't being precise, but b) is true for Boost.Function. In Christ, Steven Watanabe
