LGTM.
Just a question. In your regression test, you first define (add-one-
score
#f), then you set! it to a lambda function.
Is that solely so that you can have pitch defined in the lexical
scope but
outside of add-one-score? Or is there more going on that I haven't
figured
out?
Yes, that's to build a closure.
Now, as there is only one function using pitch, it can be simplied to
(define add-one-score
(let ((pitch 0))
(lambda (parser) ...)))
