Ability to comment out lines inside formula / calculation

Some formulas get very complex and I’d like to be able to add comments inline (just like you would by using // in javascript or <!-- in html) to give context on why certain formula logic is done the way it is, or so you can quickly test different formulas without having to remove unused logic each time.

I know there’s already a description field, but that is for the entire formula and doesn’t provide the specific line-by-line context I’m sometimes looking for.
