Thats the point: the mental model is irrelevant unless it causes bugs when you use it wrong.

Does it? Does it actually cause bugs?

Not, “in general”; You’re just doing the same thing again here and doing vague hand waving. What actual bugs? What types of bugs?

Be specific

(yes, it does cause bugs, but see how this conversation is pointless when you don’t provide any details? Right, now go read the first post in this thread.)
