I think this is essentially the same bug as #89, but I’m not completely sure. The issue seems to be that, when solving Show (Cons b a), the typechecker isn’t smart enough to realize it doesn’t need to solve Show (Cons a b) again, since that’s the constraint it’s currently solving, and it should simply tie the knot instead.

Yeah, I thought #89 looked similar but wasn't sure because that one involved a more complicated situation (classes + instances) while this was a fairly simple datatype.
