I think you need Partial Class Definition. It has been requested before 
but hasn't got much traction:

I think it's a very useful feature for external code generators. For 
example:

* GUI code generated by a form designer stored in a Form.designer.d
   file.
* Record structures generated from official specs (Something I've
   personally dealt with in C# and CodeSmith and partial classes did
   wonders).
* Model classes generated from a Database Schema. Very useful when the
   schema changes and you have to update your database.
* etc...

I would really love to hear how difficult it would be to implement on 
DMD or GDC because I really have no idea. Adding it to the language is 
another matter.

Cheers.
