Line 67:
I'm still not seeing what (fix f') should produce here, which was my original question.
 
If the answer is 'fixY can only be defined over recursive functions like plus', don't attempt to take the fixpoint using Y of a non-recursive one like f' then it makes sense to me. But that means it's not actually a generalised fixpoint combinator, is it? It's only the fixpoint for a very small subset of all possible functions which play by the rules.
