I argue the exact opposite! C++ the programming language leaves way too many decisions to the compiler implementer. A better specified language, such as Java, Ada, Eiffel, etc, doesn't have that problem of different compiler interpretations of the standard.
Interpretations of the standard? C++ standard has few ambiguities, hard to come with many interpretations. Perhaps you mean the bits that are left as implementation-dependent? I think grandparent was talking about dumb programmers who argue about precise results of undefined behaviour.
