* Work last kinks out of qualified constructors and destructors
* Low-level threading support with shared; change language to match TDPL 
(that means e.g. shared/synchronized methods is at class level, not 
method level).
* Minor touches such as user-defined operator '$', @disable etc.

Work that is not quintessential for using D but very important:

* Finish typechecking for SafeD
* Make SafeD == CompileTimeD

We should put this list somewhere.

* Define allocator abstraction
* Overhaul std.container to use it; add classic containers to 
std.container (doubly-linked list, hash, deque)
* Define streaming abstraction (already in my head)
* Add high-level networking (Jonas, where art thou?)
* Redo xml (Tomek)
* Many other changes and additions
