I wouldn't put it that black on white. Orthogonalising implicit state is just great for managing complex behavior. It's a very powerful tool, and it can be made foolproof on lots of cases.

But if two layers do IO, you'll almost certainly want the state to be explicit.

I don't think foolproof costs all that much, especially if it's habit. YMMV.

I have a BluRay player with Java(tm). If it sits more than a day or twenty, I have to unplug it, count to ten and plug it back in. I have a TV that has seizures - loud, painful seizures ( that always test the ability of an amp connected to it to defend itself ) . Scares the crap out of the dogs.

This is not necessary. This is not good.
