Hi

I’ve just posted a DrRacket2 issue on the RFC’s github https://github.com/racket/racket2-rfcs/issues/96

I’m up for anything that will reduce indentation in Racket.

• define* (https://github.com/racket/racket2-rfcs/issues/46) could avoid introducing let.
• #:let in cond could avoid nested cond (from Exercise 6 of https://school.racket-lang.org/2019/plan/mon-aft-lab.html):

(define (foo xs)
  (cond
    [(empty? xs) #f]
    [#:let item (expensive-function (first xs))]
    [(< item 0) (error 'invalid)]
    [else (+ (sqrt item) item (sqr item))]))

• Tail Indentation that Hendrik Boom has brought up several times on the mailing list, along with @rokitna’s implementation of https://docs.racket-lang.org/parendown/

Is there any common element that we can use as a guiding principle for the new syntax to avoid excessive indentation?

Swift’s guard clauses are something I find really really useful in reducing rightward drift
