I could go either way on that. It's not hard to imagine it as a recursive algorithm, and using the recursion limit provides a simple configuration escape hatch if someone has a desperate need for something wrapped 3000 times for some strange reason. But it may also be somewhat surprising if someone sets a really high recursion limit and suddenly it behaves oddly.

I've made the PR with getrecursionlimit() for now, but I'm happy to change it if people prefer it the other way.
