This C code is what I'm talking about:

file1.h:

#define BLAH

file2.h:

#ifdef BLAH
int foo();
#else
char * foo();
#endif


main.c:

#include "file1.h"
#include "file2.h"

Note how including file1.h affects how file2.h is processed, with no  
control given to file2.h.  But in D this cannot happen, a module is  
consistently processed, no matter how it's imported or in what order.   
Therefore you can be confident that no matter how it was imported, it has  
access to the same exact compiled code.

Neither static-if or string mixins cannot affect a file that does not  
import them (directly or indirectly).
