I've just pushed a bunch of Core-to-Core optimisation changes that have been sitting in my tree for ages. The aggregate effect on nofib is very modest, but they are mostly aimed at corner cases, and consolidation.

Thanks for trying to do that. Unfortunately, this seems to have introduced some other sort of corner case. Making reverse (and unfoldr, but I'm pretty sure that's unused and hence irrelevant) fusible now makes n-body allocate 1100% more. I haven't looked into why yet. David
