Instead of "kep", if you want something that visually stands out, there are also lots of fun little symbol-like characters you can use, even when you're dealing with a language where identifiers are limited to ID_Start/ID_Continue (e.g. Javascript, Rust). My favorite collection :)

But how do you discuss code issues verbally with others?

[aragonite]

If you must pronounce them, all the characters I listed are, in fact, pronounceable (as you can verify by googling them & visiting their Wikitionary pages) since they aren't actually symbols but letters from the alphabets of different languages. :)

No multicoocular O? And try Luwian for a real kick: the cutest script.
