Yes, exactly. This patch is the kind of change we tightened our compiler requirements for. We do already warn about this though. Makes me wonder whether we should make it an error instead, so that people upgrade their dependencies when we bump the minimum version instead of the patch where we inevitably break something for older compilers.
