Correct, but practically, it doesn't matter. If you compile C89, you use gcc in that mode, if C11, similarly. With Python, if you want Python 2, you run Pytho

Correct, but practically, it doesn't matter. If you compile C89, you use gcc in that mode, if C11, similarly. With Python, if you want Python 2, you run Python 2, if 3, Python 3. Backwards compatibility is another issue. IDK if people really build say C89 code with C99 or C11 compilers or use multiple standards concurrently in a given project.
