I've heard that before. So, if directory traversal is only for import 
expressions then it should be fine because importing two files cannot be 
less safe than importing one file. So, we need to let the compiler know 
that we will import, nothing fancy:

   // Mapping from file name -> content
   string[string] contents = static import("my/dir");

Note the clever :o) use of 'static' which means "directory" in this 
case. :o) Now we have all contents as an AA, ready to be parsed, 
mixed-in, etc. But I this is not important at all. Build step is just fine.
