This patch fixes issues 1203 <https://cplusplus.github.io/LWG/issue1203> and 2534 <https://cplusplus.github.io/LWG/issue2534>. 1203 hasn't been adopted by the standard but was already partially supported. I think it is better to fully support it (which cannot break existing code) rather than remove partial support of it which will remove functionality people may rely on.
