    > Note that programs were usually typed on as few lines as possible, because they had to be punched to punched cards or typed in at a teletype which echoed its input on paper.

    I suspect this is the real reason behind "cram all the closing parentheses together on the same line" rule.

    The only rationale I've seen online is in Taylor Campbell's style guide:

    > Absolutely do not place closing brackets on their own lines.

    > ...

    > Rationale: The parentheses grow lonely if their closing brackets are all kept separated and segregated.

    Yeah, right.

    Anybody know anything about how this rule came to be?

      Heh, I remember that and personally answering no when he complained about my paren formatting. I miss that channel.

      This drives me nuts. I love LISP but refuse to pretend writing `)))))))` is reasonable.

        Why are you writing ')))))' instead of your closing parenthesis being autogenerated. Sounds like a recipe for failure.

        ))))))) isn't so bad, but )))))))) is just getting ridiculous. You have to draw the line somewhere

        picolisp has an interesting solution to this. A single ']' will close all open )'s for that block of code

          That has to be a nightmare for parsers lol

            not really. it's just pop all of the stack and return to depth 0. you can still detect imbalanced parens, but i'm not sure how it affects the provenance question of where a missing one would point out in errors.

    This is somewhat confusing as there is a fairly well known toy Lisp interpreter called Lispy written by Peter Norvig
