The name of the -Wno-gnu-string-literal-operator-template option implies that Clang emulates a GCC extension. You should check that the extension has been proposed for standardization. I suspect it hasn't. Your library extension could not be accepted until after core language support has been accepted. For a core language proposal, it might help to include information about the experiences of folks who have used this extension in real life. Its cross-platform support suggests there may be such projects in the wild. To be sure, strings can easily push the scalability limits of parameter pack expansion. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
