Hi Hans,

Thanks for the quick fix of today's upload. I could typeset your examples with \mathopen, \mathclose and these are great features in order to fine tune the spacing in math mode.

Regarding the new command \Uover, I thought maybe it would be more consistent to have the usual structure ${1} \Uover {2}$ like the more friendly ${1} \over {2}$ instead of having

That would involve backtracking and be a psin in the butt wrt control. One can't have it all.

$\Uover{1}{2}$ which is more like the \frac structure.

Watch out: these are low level primitives (it is actually a set of primitives that put stuff on top of each other). The \frac is the interfaced variant.

Also a structure like $\Uover style \textstyle{1}{2}$ seems a little bit far from the usual ConTeXt atmposphere… Would it not be possible to have ${1} \Uover[style=textstyle] {2}$ instead?

That is what we have frac for (and one can define veriants that have set styles).

In any case, thanks a lot for the constant addition of cute features… Some of these engine level extensions have been on my list for a while and eventually make implementing the user interfaced wrappers nicer (and sometimes more robust). Some is actually possible because some engine internals are a bit reorganized.
