The old `letrec` implementation used the R5RS macro with `undefined`, which differents from Racket's `letrec` in that no variable is initialized until all right-hand sides are evaluated. It turns out to be simpler and produce the same effect to use `letrec-values` with a single clause: `(letrec ([x e1] [y e2]) ....)` -> `(letrec-values ([(x y) (values e1 e2)]) ....)`. |
