Speaking of pedants, recent interview one guy (their 'senior scientist') spent the whole hour tossing pedantic nits at me. What about RESTful interfaces? Are they an API or not? Ha! They're not 'procedural'! Guess what this tiny recursive algorithm's parameters are for? I don't know, whatever you use them for. I would never use a recursive algorithm in embedded work (suicide). Ha! Ha! Its the identity value over the virtual function! Ooookay. Good for you. I'd convert it to tail recursion, then a simple iteration, and never need that value.

Needless to say I didn't connect.
