   @jwfromm this pass should be used in conjunction with the gradient pass. Since tensors for reverse-mode ad are instantiated as 0-filled tensors but are actually not useful during the forward pass, this PR should reduce memory allocation by 50% during the forward pass. I don't have any data on this but mathematically this would make sense
