I do want to be pedantic, but not in a fair way :) The C++ 11 standard was not required to standardize broken garbage from many years ago. WG21 pulled C++ 0x

I do want to be pedantic, but not in a fair way :) The C++ 11 standard was not required to standardize broken garbage from many years ago. WG21 pulled C++ 0x Concepts (a much more powerful feature than the "Concepts Lite" which landed in C++ 20) because they argued it might take too long to implement, ridiculous as that claim is, so there's no reason to keep something terrible just because it's in a draft paper.
