Just the expected speed decrease. Cheers -- Matteo- If the old object is not thrown away, then memory consumption is doubled and the "fast" argument is wrong. (Performance, of cloning an object without copying values and of some method calls, is negligible.)I'm not sure that anyone has benchmarked the memory impact of the immutable approach yet. I will pass that along and see what data comes out.
