I actually posted that comment as a joke (notice the typo) and I agree that this is just a matter of style; but there is some seriousness here. I remember reading in [a book](https://www.amazon.com/Enough-Rope-Shoot-Yourself-Foot/dp/0070296898) a suggestion to use a spelling checker on your code just to avoid silly misspellings, and of course then to make sure your variables are actually spelled correctly.
