I REALLY don't want the whole compiler, but something like the above isn't too bad IMO. Perhaps the NTTP recursively takes a type template. WHILE that isn't super easy to read, it isn't all that bad, it is pretty much the template head. https://github.com/llvm/llvm-project/pull/123736 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
