If we can create partial module, it will be easier to use. then 
no package needed.
such as:

################
// test/foo/gui/button.d
partial module foo.gui;

class Button
{
     public this() {
         import std.stdio : writeln;
         writeln( "New Button!" );
     }
}
// test/foo/gui/widget.d
partial module foo.gui;

class Widget {
     public this() {
         import std.stdio : writeln;
         writeln( "New Widget!" );
     }
}

// test/foo/namespace.d
module namespace;

import foo.gui;

void main()
{
     auto w = new foo.gui.Widget;
     auto b = new foo.gui.Button;
}
