    void foo()
    {
#ifdef foo
        doSomething();
#  ifdef bar
        bar();
#  else
        notBar();
#  endif
#endif
    }

works, too.
just see the hash in the first column as a different "syntax space"
(which it is), and then it makes perfect sense.

there is one exception: #pragma and some other directives are sometimes
passed through to the compiler, i.e., they are only "fake" preprocessor
directives and in fact _kind of_ belong into the proper code stream. one
could bikeshed this to no end ...
