Comment (by sirinath):

 Thought memory is not manually managed does not mean that memory can only
 be managed in a language like Haskell though a GC. GC can be fall back.

 At the language level there may be no distinction between value and
 reference under the hood they are either on the stack or heap. The heap
 has to be managed. Also allocation / de allocation can be in bocks in
 Haskell opposed to object at a time based on memory allocation in
 execution locality. Allocation and de allocation can be executing thread
 by inseting these into the flow of the program at the compiled code level.

 ARC in Objective c context cannot be implemented as it is in Haskell.

 Romacing with the GC is more of a philosophical decision with current
 state of compiler technology. Some years back gc would have been the only
 option for languages without explicit memory management.
