A solution could be to allow this:

----
module foo {
     module bar {
         // equivalent to foo/bar.d
     }
}
extern(C++) module bar {
     // Equivalent to namespace bar {} in C++
}
----

Note that Rust does something similar to this to allow multiple 
modules to be defined in a single file (though Rust also doesn't 
have the correspondence between filesystem location and module 
like D does - perhaps this is acceptable with the introduction of 
package.d?)
