Java updates
Seeing how much D borrows from Java, I think you may be interested in seeing some of the updates of Java:
http://hamletdarcy.blogspot.com/2008/12/java-7-update-from-mark-reinhold-at.html

Some of the most interesting changes:
- Safe rethrow - Allows a broad catch clause, with the compiler being smarter on what you're allowed to rethrow based on what is thrown from the try block. (I had not seen this before but it looks nice) (I don't understand how this can be done).
- Null dereference expressions - Null checks with '?' syntax similar to Groovy... lettign developers avoid a nest of null checks. (This will probably come in D too, sooner or later).
- Compressed pointer 64 bit VM (This is very useful, but I think it's not easy to do in 64-bit-D with pointers. References look more doable).

Compressed pointers would just have to be a new type.  But it's more
likely that we'd just create a struct for this in D, seeing as how we
have opDot now.

This is something Java desparately needs, as damn near everything in Java is 
nullable. I'm not sure I would argue against it in D, but I would say Java 
has much more of a need for it than D does. I was looking at the 
ANTLR/StringTemplate code a few weeks ago (it's written in Java) and there 
were so many null checks all over the place that I felt like I was looking 
at code from the time before exceptions replaced errors-as-return-values.
