This. If your shell script is so long and/or nested that you want
folding, then you’re much better served by rewriting in a proper
programming language. My personal rule of thumb is, rewrite if you
want to do any arithmetics, or arrays, or the script no longer fits in
a single screenful.

A similar point goes for other programming languages: If you want to
fold parts of a function, the part you want to fold is a candidate for
extraction. If you want to hide some functions while looking at
others, maybe split your module.

A working folding facility can be a painkiller when working with
existing code. But don’t become addicted to painkillers.
