Make the definition of a function with a required keyword expand in a way that allows the optimizer to recognize it as a form that has no errors or externally visible side effects. The old expansion of (define (f #:x x) ...) included (define lifted-constructor (make-required ....)) (define f (lifted-constructor (lambda ....) ....)) where `make-required` calls `make-struct-type` and returns just the constructor. The new expansion instead has (define-values (_ lifted-constructor _ _ _) (make-struct-type ....)) (define f (lifted-constructor (lambda ....) ....)) In other words, `make-required` is inlined by macro expansion, so that the optimizer will be able to see it and eventually conclude that no side effects have taken place. |
