The problem is that we don't have a time machine, so we can't go back and fix code that existed before the feature. Even I trusted a tool to do a global replacement in my own source code, which I can inspect and confirm correctness for, and everyone else did the same, there are plenty of old releases of all frameworks still in use and people with legitimate reasons not to upgrade. I wouldn't run such tools it for third party codebases and don't expect most people would either. It would be a maintenance nightmare. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
