Essentially, what I'm saying is:

mod1.d:
int x;
extern(C) static this()
{
   x = 5;
}

mod2.d:
import mod1;
int y;
extern(C) static this()
{
  y = x + 1; // should be 6, but could be 1 if executed in the wrong order
}

Druntime knows how to make this work. C does not. You are changing the semantic
meaning of static this() by putting an extern(C) on it, and I don't think it's
a good idea. People are used to this "just working".

You also likely will break code, as I think there are many files with
extern(C): at the top, for which this would change the semantics.
