$ find
main.d
foo/hello.d

$ cat main.d
import foo.hello;

$ cat foo/hello.d
module foo.hello;

Ok so now let's say I rename the directory "lib" to "foo". If I 
don't change the "import lib.hello" to "import foo.hello", how is 
the compiler going to find "hello.d"?
(As a reminder, as I said, I'm using separate compilation)
