Can we get an implementation of equal? that works for recursive structures per r7rs? It doesn't need to be called equal?, it can be called equal-shared? for instance.
Yes that would be interesting to have.
I have an initial implementation that works with shared structures, but there is an edge case: If there is a shared object in the structure (without recursion) it needs to be eq? to its counterpart.
Have you looked at how other implementations of Scheme do this?
