I'd like to do more in D 2.0, but if the libraries I need aren't ported, 
it's either spend a lot of time porting them myself, or stick with D 1. 
  Right now D1 seems the better option.  But since D1 isn't getting new 
features I suspect there will come a point when D2 gets something so 
utterly cool that it's worth doing whatever it takes to use it, 
including maintaining private 2.0 forks of other people's libraries.  Of 
course by then they might have already ported... so I might as well wait.
