Any more progress regard this? Dynamic arrays and associative 
arrays are very useful even in a betterC environment. Wouldn't it 
be better to rewrite the dynamic arrays to use an internal 
storage struct using atomic reference counting similar to C++ 
strings (at least in some previous implementations). This way 
arrays are only dependent malloc/free. Using the reference 
counting, slicing would be supported just as before if I'm not 

I also don't think this should be special variant of druntime. 
Reference counted dynamic arrays could go into the full D 
language as well. This would probably even reduce the memory 
consumption compared to the current GC implementation.
