As in "Fixing Letrec". This improvement corrects a performance regression with the revised expansion of R5RS `letrec`, which wraps right-hand sides with `values`. Besides detecting effect-free primitives, we have to fix the treatment of the right-hand side for a multi-binding `letrec-values` clause. For now, we conflate all of the bindings in a single clause. |
