Huh, yes.
The current version behaves ok for sequences mainly constructed with fromList, cons or snoc; a sequence made up of 'append' is strict.
Would it be possible to change this behavior?
Sure. I attach the modified version, for reference.
Ross's point about requiring append to be strict in order to guarantee O(n) toList is a good one. In fact, the current implementation isn't quite correct: either fromList should be strict, or append should check for an empty Many constructor. Cheers, Simon
