Can you give an example?

I’ve found that many Racket libraries more like #lang racket/base (require racket/list) (require ...) than #lang racket Why? Is there any benefit of using racket/base ?

Better start up time

Try time racket a.rkt (your first program) vs time racket b.rkt (your second program)

Thanks!

I just tried: $ time racket racket.rkt real 0m0.523s user 0m0.000s sys 0m0.000s $ time racket racket-base.rkt real 0m0.212s user 0m0.015s sys 0m0.000s You are right :+1:

In addition to better start up time, I find it useful to get a clearer idea of dependencies, so having explicit require statements is informative.

Ooh! I think I found a description of what I’m trying to ask about for Racket. Well, it’s the description, it doesn’t really help with the question of if/how Racket could do it.
