Well, except for maybe a language that doesn't force you to remove (temporarily) unused imports and change your variable name to an underscore if you simply comment out the only section of code that used to refer to it, making your variable freshly un-used. I find there are some highly opinionated, unconfigurable aspects of the language that pretty much only waste time. They actually get in my way constantly.

I agree completely. It's so pragmatic. It's not sexy. It just does the damn job, and that's why I love it.
