Perhaps we have to deprecate auto? ;-) -----Ursprüngliche Nachricht----- Von:Ell via Std-Proposals <std-proposals_at_[hidden]> This was discussed on reddit recently [1]. As noted there, the problem is broader than just dangling references to temporaries. The presence of unintended references is itself an issue: auto [min, max] = std::minmax (x, y); // x and y are lvalues std::swap (x, y); // oops, also swaps min and max I'd be wary of special-casing just the rvalue-argument case.
