I wish this had a better language name than just "lets-go". How about "clogo" ?
Naming is hard but I like let-go, it's a layered pun :) (let [...] (go ...)) It lets you let in Go! Clogo is a no-go for me. Maybe you have some other ideas? I'll consider good ones :)
I'm relieved that clogo is not an option for you. It has some strong, malodorous campground toilet connotations to my foreign-language-trained ears. Loogo? Pottygo? Go number 2? Yikes to all of those.
And now, as bonus content, for something completely different: https://youtu.be/M3-51DhOzHE?
