Can we just have struct inheritence already?

D has a TON of features. And yet every single day, people demand ever more 
features. How can this possibly work without turning D (and the compiler) into a 
unusable mess. I have no choice but to constantly say "no".

As for struct inheritance, it seems what Manu really wants isn't struct 
inheritance at all, it is zero sized structs having zero size when they are used 
as fields.

First off, he has a workaround for it. I agree it's not very pretty, but it 
works and he is not blocked. That moves it way down on the priority list.

Secondly, there are template mixins, which have zero size.
