Hey y'all! I was wondering if it's possible to make variables defined in let blocks mutable? I'm currently using this little workaround but I'm hoping there's a better way
(let [data {:drawdata []
:linenum 0
:workinglen 500}
lineheight 20]
(set! (.-linenum data) 1))

By design they are not mutable, this is against Clojure's design. If you need mutability, you can indeed use a mutable object, or an atom

Makes sense. Wasn't sure if there was a reader macro or something. Thank you!
