Won't using -nogc preclude using this in Phobos/Druntime?

How about instead of a new switch, change the name mangling of 
anything that inherits from RCObject? E.g. 'C' is used for 
classes, 'R' could be used for reference-counting classes. Then 
an ordinary version block can be used to switch between the two.
