Oct 26, 2015 at 21:38 comment added Peter LeFanu Lumsdaine This example is beautifully different from most of the others. The others give examples of clearly non-natural families of isos. This one feels much more like it ought to be natural — even with the counterexample in front of me, I find it hard to disbelieve that these functors are naturally isomorphic.
