Yep.

Since some D types don't exist in C and so have to be passed 
differently by convention (static arrays), I think an argument 
could be made that we should assume that anything behind an 
extern (C) interface is in fact C code.  But that's not how it's 
treated today, where extern (C) is simply another calling 
convention.
