 good answer!   Having worked on a lot of embedded microprocessor systems over the years... that's exactly the kind of thing you don't want and sometimes all too easy to do by mistake when writing C or assembler!
Good answer!

FWIW, I say "effect" rather than "side effect" when talking about
Haskell, because in Haskell effects happen when you want them, not as
an unforeseen side-effect as a result of the complexity inherent to
the source code.

It is often said that having an effect is "difficult" in Haskell. But
really, it's just that if you are launching missiles in Haskell, *you
actually mean to*. It didn't happen because you wanted to increment i
and then "oops, stuff happened".
