I have been playing around with the features presented in the example file sent by Mikael, and I must say, among other things you have implemented, the constructs \bearkhere and \skiphere, and friends, are absolutely great, brilliant and so simple! I wonder why such a simple and elegant solution was not around before…

they were to some extend (in split=text mode) but never advocated but we 
added some to it as well as made it work with diferent alignments (most 
noticeably slanted) and number placement (overflow)

just think of the side effects:

    {a}\over{y} + z

y and z are combined so one need to add { }


thenm infleuncing styles becomes trickier too; the lot becomes an ord 
(ok, not in lmtx, where it becomes a fraction atom) and when you compare


you even save two keystrokes -)

it's also not easy to control spacing etc because one cannot redefine 
over; actually fractions uses \U[..over|above|..] which takes two 
arguments (forward scanning)

> It seems that the \choose construct has been ditched but I did not guess what has replaced it (I guess the reason is the same for ditching \over, since the construct used to be ${n \choose k}$ and this is not what one wants to have in a macro).

some of these were just old school simple things but we have better 
alternatives; and if not: just specify what you need and we will come up 
with something (configurable)

(of course one can just define the old schoose)
