I haven’t used clojure in quite a while but what’s the issue with (let [a b] …)? Is (let (a b) …) even valid clojure?

I haven’t used clojure in quite a while but what’s the issue with (let [a b] …)?
Is (let (a b) …) even valid clojure?
- everforward 5mo agoI believe it would be (let ‘(a b)), but I’m not sure if that’s valid or not. That’s how Racket does its version of defn
- acdw 5mo agoIn CL and Scheme, it's (let ((var1 val) (var2 val)) body...). So parentheses are used for grouping and function/macro application. In Clojure, parens are just used for application, so you have e.g. (let [var1 val var2 val] body...), or (defn foo [x] ..) or (cond testa 1 testb 2 ...). It takes some getting used to, and I do wish Clojure would do something more like (let [[var1 val] [var2 val]] ... .. though of course then you'd have to figure something else out for destructuring.
