Can author imply anything else?

Of course.

If reader knows better, why reader reads at all?

Because the reading, as you yourself said:

...may turn out to be useless, but only after the fact.

I don't find it wrong, just irrelevant.

Oh, and using "data structure" to mean a "struct" is annoying for us old farts that learned the standard meaning, it's causing people to get confused. Actually, since classes are a data structures (in the old sense), the very title sounds like nonsense.

Nothing too bad, every day people does much worse in the Internet, but add the μαιευτικη´ and it comes out as inappropiate.
