What would be the best way to work with huge class hierarchies?

[O/N/Src via Digitalmars-d-learn]

Hi
I'm trying to bring a class hierarchy with a lot of classes in D 
style.
The original classes have sometimes identical names like "button" 
or "control".
With the namespaces I've classes like followings

ui.core.Button
...and subclasses like
ui.web.mobile.Button
ui.web.desktop.Button
ui.desktop.Button
and more like this.

Which would be the best way to bring them in the D world?

Apple-Style like UCButton, UWMButton, UWDButton, UDButton
MS-style with the use of namespaces (ui.web.mobile.Button, 
ui.web.desktop.Button)
Java like WebMobileButton, DesktopButton
?
