It's a pretty canonical and uncontroversial half. A key reason things 
get stalled is because people may disagree about details, or resort to 
arbitrary gatekeeping behavior (like not accepting work when it is part 
of a bigger project that is not finished. Keeping things rebased against 
DMD master is quite a bit of work due to all the refactorings that are 
happening).

In terms of being _done_, if unpacking would really be half, it is a bit 
more than half:

Which reminds me, we should try to get it merged.

Why no PR yet? I think there is still this ICE related to copy and move 
constructors:
