for/list in-port did the trick

port->list

Loving Racket in general and Dr. Racket as an IDE in which to learn. Wondered if anything like Rainbow Parentheses (https://github.com/luochen1990/rainbow, displays different levels of parens in different colors) was available as an addition to Dr. Racket.

(Hit send too early). Hopefully, I’ve not overlooked something obvious. Many thanks for any leads!

try: preferences -> colors -> background -> parenthesis color scheme

@ben Thank you very much. Doesn’t work quite the same way, but accomplishes the same goal very nicely. I appreciate it.

Is there a way to put procedure-arity-includes into a contract-out clause?
