This topic was there for so many times.
Tuples, async/await, maybe monad (eg. int?), conditional 
dereferencing qualifier?.identifier, coalescence operator return 
x ?? 42;
better properties, default safety, explicit throw funcs, runtime 
reflection, ARC instead of GC, so support, ...

The community is quite conservative about implementing new stuff 
in D.

BTW: I decided to make my own language rather than forcing the 
community to implement something what I would like to see in the 
lang. https://github.com/Rikarin/Rin
