For example, consider:

    for (i = 0; i < 10; ++i);

some C compilers issue a warning for the trailing ; as do some static checkers. If the programmer intended that, the warning is a false negative because the C language rules allow it.

However, such a construct is a hard error in D. Whether you meant it or not, it is not allowed. This is what I meant.

A construct in D that would pass is:

    for (i = 0; i < 10; ++i) { }
