Perhaps you forgot to read the part where I said:

So now it's a good time to re-read it.
To go through your claimed advantages of the STL point by point:

I already answered that:

Who says I need that flexibility?

That's also something one can do without. I will use the static analysis
tools that work with my code, not the other way round.

This is not a straw man attack, but a direct answer to your "more speed
(algorithms)" claim. Therefore, your answer is the one that is fallacious.

And this ad hominem attack is not a useful contribution to the discussion in
