The standard library is a better place to put manual memory management  
than user space because it should be done by experts, peer reviewed and  
then would benefit everyone at no extra cost.

There are likely a number of smaller GC allocations which could be  
replaced by calls to alloca, simultaneously improving performance and  
avoiding GC interaction.

These calls could then be marked @nogc and used in the realtime sections  
of applications without fear of collections stopping the world.

Neither ARC nor a super amazing GC would be able to improve upon the  
efficiency of this sort of change.

Seems like win-win-win to me.

Excellent :)
