Move-assignment and reference member

Question

Copy-assignment for a class with a reference member variable is a no-no because you can\'t reassign the reference. But what about move-assignment? I tried simply mov

In general if one wants to do non-trivial stuff with references in C++, one would be using reference_wrapper, which is essentially a fancy value-semantic stand-in for a T&, then one would be done with it - it already provides (re)assignment and other operations. I'm sure that would make move constructor and assignment near-trivial, if not trivial (note not trivial as in per the is_trivially_* semantics).

"Reference wrapper" is added to C++03 as part of TR1, and is part of C++11.
