I think I had a few misconception about D interfaces. The 
documentation does not say anything about interface inheritance, 
but it seems to work when I tried it. It definitely seems weird 
that this behavior isn't mentioned anywhere.

Also, the use of static* or final methods in the interface can 
allow default implementations of methods. This is something that 
can be done with Scala traits. I feel like this isn't 
documentated as well as it could be. A weirder thing is that when 
I tried to test that static and final methods could not 
overridden (which is allowed in Scala), it seemed like they were 
getting overridden. The tricky part is that I had been using 
something like final foo() { } instead of final void foo() { }. 
For some reason you can override the first, but not the second.

So really, I guess the D interfaces are more powerful than I had 
thought. Only downside is that they only work for classes.

* I feel like these also aren't particularly described well in 
the documentation either.
