I've been doing functional programming so long that I genuinely have a hard time thinking about how I would write things without recursion. Like, I technically know how to convert a recursive algorithm to an iterative one, I've done it before on more resource-constrained stuff, but I don't like it. I think the recursive stuff is generally prettier and for 99% of things it's fast enough (and 100% if your compiler supports tail recursion, though you'd still be stuck maintaining a stack for most of the more interesting stuff). Occasionally I'll do things to force myself to learn how things were done before I was born. I've been on/off hacking on a Commodore 64 game, but man I feel pretty grateful to be as spoiled as I am with fast, cheap, easy-to-use hardware.
