It doesn’t have to pretend anything you don’t want. If you don’t want this kind of problem/failure possibility, then you have to encode those states in the type system. Functional programming can do the same things you can do in imperative, but you gotta make it when it’s not there. Just like in any other paradigm.
Totally fair. As I said up thread, I am comfortable saying I am imagining bad examples here. Would be interested in reading good examples. Though I couldn't find any of the bad ideas I had in my mind, I also didn't find any good ones on a quick search.
