Is it really tempting for people? They've given me too many headaches when I've had to reformat or add functionality to files.
Unless it's a simple single use script that fit on the computer screen, I don't feel like global variables would ever be tempting, unless it's for constants.
Depends on what you're doing. Functional programming has its own downsides, especially once you want to write interactive programs, which often depend on global states. Then you either have to rely on atoms, which defeat the purpose of the functional programming, or pass around the program state, which is janly and can be slow.
I personally go multi paradigm. Simpler stuffs are almost functional (did not opt for consting everything due to performance issues), GUI stuff is OOP, etc.
