We are pretty good at picking out variable names too... Especially if the grammar itself is highlighted since we then know exactly where to look / where not to look. I'm not convinced of the argument, but still a bit curious. I sometimes highlight a variable to follow it and make sure I don't miss an instance of it, so that I totally get. But not sure we have enough colors and contrast to make sense to follow many variables without cluttering everything up. A compromise might be to manually color up to 3 or something variables. ... but the cases where that helps may be a sign that the code isn't very readable to begin with (helping with messy codebases is a proper usecase though!).
