Make it 63 (31?) to align with what C99 can distinguish.
Also: I really like unicode in identifiers. So if at all possible don’t just have a random string of letters and numbers, make sure to include greek letters and all the funny emojis. (I just forgot which languages and compilers etc allow that.)
For extra fun, you can name your variables using solely Unicode invisible characters (e.g. non-breaking space) so they’re impossible to visually distinguish
You should really be naming all your variables by generating 64 character (minimum) random strings.

Who needs private variables when you can generate cryptographically secure variable names? Much better security.
