Linus Torvalds disagrees about line lengths for what it's worth: https://news.ycombinator.com/item?id=23356607
Plus, with code completion (especially in a strongly typed language) it’s no longer necessary to optimize for fewer keystrokes.
But what has worked better for me is to have it as a soft not a hard rule. Better to have some lines go over a bit than having awkward breaks that make it harder to read
Strict rules are BS because they count characters that don't contribute to the actual content that you're parsing.
This includes punctuation and especially whitespace. I tend to keep lines short in general, too, but strict limits just for the sake of it are indeed more hinderance that helpful.
