Yeah, legacy code is like a crag that’s seen better days – the holds are cracked, the rope’s frayed. Fixing a bug is like finding that one solid piece of gear you can trust, locking it in, and feeling that whole route tighten up. But if you skip a step, you’re dropping into a pitfall you didn’t even know existed. Punch cards? That’s the ultimate rappel, only the rope is made of waxed paper. Keep the line clean, the gear tight, and you’ll reach the summit before the whole machine breaks.
