To my understanding, partial classes were introduced by Microsoft to 
make it easier for *them* to rewrite the UI code coming from a designer 
without having to watch out for user code. That is, whenever you change 
controls in the designer, now they just need to rewrite the .designer.cs 
class and not worry about erasing or skipping code you defined besides 
UI code.

Conclusion: the motivation is coming from the UI, and to make life 
easier for them. (Maybe there are other reasons? I've been programming a 
lot in C# lately, and I never needed a partial class)

Since D doesn't have a UI designer or nothing is integrated that much... 
what would you use partial classes for?

If it's not for that reason, I think it makes it harder to know where 
is defined the code you are looking for.
