I looked into this to fix #2876. While trying this patch, I remembered previous discussions that we cannot in general prevent infinite loops during typechecking, and was expecting this to fail.. but I got an everest green with it, and the problem in the bug report is gone (the assertion fails to encode due to the inner let rec, but doesn't crash).
Given that all of our code works with this patch... should we take it?
