Cocoa (NeXT's/Apple's framework for Objective-C) uses a very successful 
and well-thought-out delegation pattern, whereby GUI elements 
representing large amounts of data, like table views, have delegates 
(not in the D sense of the word) that provide them with the actual 
contents. Granted, Objective-C's runtime is much more dynamic than D, 
but a simplified version of such a pattern could still work in D. After 
all, user interfacing is typically where dynamism is more important than 
speed.
