1. Every library for D will have to come in two versions. One which works, and 
the other is likely untested. This will divide the D community in half.

2. RC and GC engender different styles of programming. The idea that one can 
successfully switch between them with merely a compiler switch is a fantasy. You 
cannot write non-trivial programs that function well and pay no attention to how 
memory management is done.
