d future or plans for d3

[Froglegs]

  I've only recently tried D out, but what I'd like to see..

-GC being truly optional
-being able to specify if the standard library should use GC or 
not, perhaps with allocators
-if D is going to have a GC, then a precise, compacting one would 
be cool, but not if it gets in the way of making the GC optional


  One thing I'm not sure about, D classes are virtual by default, 
but if you mark all functions as final does the class still 
contain a VFP or any other cruft?
  Also why are class functions virtual by default? My experience 
in C++ is that I rarely use virtual, so I don't really understand 
why that is the default.
