You certainly can build and run testcases with Apple's compilers to compare behavior (without looking at the sources), just as people looking at C++ tests exercising corner cases of the standard routinely compare with how EDG handles those areas (without having access to EDG sources). Independent implementations are of value in deciding how a language should be defined if it is not to be a language permanently defined by a particular implementation. -- Joseph S.
