Hello everyone, I’ve just started reading The Little Schemer and I believe there are many who read this book here. I have a very trivial question. What could lat stand for which appears in Ch2? (I know what it does but I’m wondering about the etymology.)

fyi, this is lat? https://stackoverflow.com/questions/35612678/is-lat-a-primitive-function-in-scheme

(l) of (at)oms

:+1: thanks @jesse

I need to run (dynamic-require "a.rkt" #f), …, (dynamic-require "z.rkt" #f). Each script runs quickly, but the overhead of dynamic-require for each instantiation is a lot. Is there a way to reduce the cost?

Try making a module “a-to-z.rkt” that just contains (require "a.rkt") … (require "a.rkt") and then use dynamic-require to dynamically require it.

@sorawee are you doing them all in the same namespace? dynamic-require doesn’t really have any extra overhead

Good point. It’s all different namespace.

if the all load a bunch of other code, then sharing the namespace will help a lot

So many coded information, IMHO, list-of-atoms? is so much better. :zany_face:
