> After writing Clojure for a few years, there were several times where I ended up with a complex function with unbalanced parens, and the only way I could fix it was to basically re-write the function piece by piece. That's the punishment for removing some of the "reduntant" parentheses from Scheme. Compare Clojure: (let [a 1 b 2] (+ a b)) Scheme: (let ([a 1] [b 2]) (+ 1 2)) If for some reason, say, `b` get deleted a Scheme compiler can tell you which binding pair has a problem. In more complicated setups, in Scheme/Racket I indent the piece of code, and from the indentation I can see, where end parenthesis is missing.
