    That's great unless you have this:

    #ifdef FOOBAR
    int foo_var = foo_init();
    #endif
    ...
    #ifdef FOOBAR
    foo_use(foo_var);
    #endif
    ...
    #ifdef FOOBAR
    foo_use_again(foo_var);
    #endif

    The C++ approach also makes ifdef'ing existing code easier -- you often
    don't have to introduce new scopes that the C approach would require.
