No, that would be a bad comparison. The Annexes are optional, i.e., not part of the core Ada language. Surely you know this. A better argument would note that the existence of compiler bugs implies that few compilers implement any standard, but this sort of nitpicking, while logically correct, is unhelpful. Due to the way C++ evolved, implementations have varied quite a bit amongst themselves, and the divergence from the ISO standard is still quite large compared to the divergence of typical Ada compilers from the standard. Whatever else you may think of Ada vs C++, I don't think you can make a reasonable case that C++ is comparable to Ada in terms of standard conformance. -- Brian
