You can like the idea behind functional programming while believing that any application is in the end about side effects and therefore a purely functional application impossible.
If you’re doing something completely deterministic and non-interactive, like computing a digit of pi, it’s great. I use Haskell semi-regularly for that kind of thing. You could argue printing the output is a side effect, but is a side effect followed by termination really “side”?
Oh, well I can agree with that.

I agree.
I think it is a side effect if it runs on a modern Os. But honestly who cares…
