Two Scala annotations

Is this stuff written somewhere in a D design rationales page?

Now that D is several years old, how much Java code was ported to 
D? (Despite there is no mechanical Java->D translator yet). Was 
this automatic translation desire worth the troubles (like inner 
classes, like the risk of killing switch optimizations by 
mistake)?

This post is about two Scala annotations. If that's not a bug, is 
something like that first Scala annotation useful in D too?
