I doubt anyone would disagree that triple negatives aren't easy to parse.

It's not the triple negative that is the culprit here though. It's the inherent ambiguity in a phrase such as "never been better", which could be either a negative or positive statement. I'm sure there's a name for that construct?

I think tptacek's sentence would need a 'than' to have a valid reading as a positive statement. 'never been better' is ambiguous by itself, but by the time you put it into a sentence it may or may not be ambiguous.

So my answer is mu.

If that sentence hadn't mentioned triple negatives, I don't think I would have noticed anything abnormal about it.

Now I'm curious how natural language parsers handle triple negatives.
