And if most of your code looks like that you are making a mistake.
"Sometimes I need multiple lines" is fine, exceptions happen.
But again I ask, visually are those lines super different?
Ditto for things like for loops which have multiple statements in a line.
This isn't really true. Most non-Lisp languages I work in, like JS or Ruby or Python, have things like long_expression =\n long_other_expression, or long_expression\n.another_long_expression\n.another_long_expression.
