Hello, For the ones not listening on tex-implementors, please note that, as announced, I have created a new engine called: Prote, that consists of a change file to be applied after etex.ch and before system dependent changes. It is like e-TeX: compatible with TeX; one star adds e-TeX features; two stars add Prote features with, for now, the LaTeX required extensions. The stuff is considered alpha (the change file applies; the result compiles; it passes the---adapted---TRIP test; and the primitives act as I understand they should). I had lots of questions about the definitions of the primitives. So I have put extended descriptions of the primitives, default cases, corner cases and supplementary questions and precisions in the draft of the manual. I'd like some of you to review these descriptions and to think about the questions so that the API will be clearly described---and that I can be sure that what I have implemented corresponds to what is expected. Change file and (short) manual are to be found here: http://kertex.kergis.com/en/prote.html (This is not publicly visible---from index.html---because it is too early for users.)
