I would have doubted this would make a difference.  However, I think
that it is better not use OO calls if not needed, that is, if
polymorphism is not needed for that function, so I think that those
patches are a good thing irrespective of speedups, for code readability.
With OO one never know which function is really called which I find
very annoying.  Even though I used quite a bit of OO in texinfo for
polymorphism, I really dislike it, but as it can help simplifying code
sometime I used it...
