OK, thanks. I will refrain to use these names. Knowing this will give me some peace of conscience :)

Yes, it is an extension of the extramarks package. Regularly, I get questions (by email or on stackexchange) that can't be solved by the current implementation of extramarks because the marks are not independent. So I am experimenting with a new implementation based on the e-tex \newmarks mechanism.
I now use the package name extramarks2 and the macro names will have 'extramarks' as module part.
It is actually fun experimenting, but I don't know if I will release the result. If the new marks mechanism becomes available in LaTeX2e, it might be easier to use that to implement it.
In the meantime, I am also learning expl3 syntax, which is more of a challenge.
