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
$\Uover{1}{2}$
which is more like the \frac structure.
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?
In any case, thanks a lot for the constant addition of cute features…
Best regards: Otared K.

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

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.

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

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.
