Yeah, I see the mountain analogy every time I hit a stack overflow. I keep a mental schema, like a tree diagram, where each branch is a single responsibility. Every function is a leaf, and the base of the mountain is my main loop. I use interfaces as the cliff faces, so the layers can slide under each other without tangling. If something starts to look like a recursion loop that never returns, I question whether it’s ethically sound to keep calling itself. If it passes the sanity check, I refactor it into a generator and give it a proper base case. That keeps the code from collapsing like a sandcastle.
