Hey, English is my 5th language, and the only language I learned as an adult, so the brain wiring is not perfect (my coworkers recognize my code by presence of "Yuriysms", like "Lable", "avaliable". etc.).
Plus, in my defense, I was just reading about parsing "ternary" operators in a compiler...

Aha! My search for ternary came up with Stack Operations using three inputs so it seemed a likely reference given the discussion (and my limited understanding of what goes on behind the scenes of programming).
