replyI 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.
replyThis drives me nuts. I love LISP but refuse to pretend writing `)))))))` is reasonable.
replyWhy are you writing ')))))' instead of your closing parenthesis being autogenerated. Sounds like a recipe for failure.
reply))))))) isn't so bad, but )))))))) is just getting ridiculous. You have to draw the line somewhere
replypicolisp has an interesting solution to this. A single ']' will close all open )'s for that block of code
replyThat has to be a nightmare for parsers lol
replynot 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.
