Comment(by tibbe):

 Replying to [comment:5 rl]:
 > Addr# is what Ptr and friends are implemented on top of. The operations
 would only be useful for unrolling, not for the pointer arithmetic.

 Fair enough. Once we have the actual unrolling going in the backends (LLVM
 will be first) we can look into it.
