Nesting is the only reason I wish to use any of these preprocessors to be honest. I don't understand how people write plain css when things like less/sass exist. Writing and maintaining css selectors is a nightmare, but it's so simple and intuitive to just nest things inside parents.
I was going to say. How the heck is nesting an anti-pattern? It is SO useful for CSS. It should have been standard years ago. Variables are helpful too.
