Interestingly, I noted I tended to use one letter variables when writing in Ruby, and the longest, most descriptive possible variable's names when writing in C#; And Ruby, I think I have read somewhere, is somewhat close to lisp. There is the readability of the language itself to weight in too, when its easy to see the important stuff, you can name the important stuff with short names. And there is the most important, what are you writing about; Strangely I always remember to myself that the only important goal is to write the slowest, most natural language, and above all, most natural/daily-life/ELI5 Logic. But always end with the logic looking like pure math notation, like if I looked at it not knowing it was me who wrote, would think is unreadable Dark Magic Math, and I end with it having zero Math or CS formal training (only highschool), so maybe it's inescapable.
