is there an idiomatic equivalent of (filter (lambda (pair) (equal? (first pair) foo)) lst)?
<bremner>
basically assoc, but return all pairs

I would say that *is* the idiomatic way, given SRFI 1

Hello #racket. I have a question about the big-bang function in bsl. I do not understand what input is handled to the functions therein. Lets say i have a function call (to-draw render). What data is handled to the render function? Here is another example: (on-tick advance-cow). What is handled to the advance-cow function?
<olavx200>
If anyone is wondering i am doing an exercise from "How to code: Simple Data"

olavx200: in big-bang, there's always a current World. For every World, big-bang creates an image by calling `(render the-world)`. For every tick, big bang goes to the next world by calling `(advance-cow the-world)` and then using that as the new World.

samth:Thanks for responding. If i understood correctly the data that advance-cow produces is passed to all the other functions the next tick. I appreciate the help
