This is fairly clearly a contrived example. Can you give an example of
actual in-use code which suffers from such deep indentation?

I've no doubt you can produce such code, but it's far easier to discuss
ways to improve (and *that* it will improve) an example of actual code
than a contrived example.

This would almost certainly be improved by taking some of those
deeply-indented parts and re-factoring them to separate functions. But
again, it's hard to show that without a real example.
