rsmith added a comment. For what it's worth, the most recent thoughts from CWG on this question are from 2015 (prior to guaranteed copy elision, which probably changes the answer): http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1965. That direction would permit `const_cast` to rvalue reference type to materialize a temporary for arrays and classes but not scalar types (which seems just as arbitrary as the current set of rules to me).
