Why \atop or \choose do not need \noexpand?
What is special about \over?
It is redefined by ConTeXt to be a useful command in text mode.
\starttext
\section[sec:test] {Some section}
See \over[sec:test]
\stoptext
Hans, is it OK to change the definitions in core-def to
\ifnum\texengine=\luatexengine
\ifx\in \undefined\else \let\normalmathin \in
\unexpanded\def\in {\mathortext\normalmathin \dospecialin } \fi
\ifx\at \undefined\else \let\normalmathat \at
\unexpanded\def\at {\mathortext\normalmathat \dospecialat } \fi
\ifx\about\undefined\else \let\normalmathabout\about
\unexpanded\def\about{\mathortext\normalmathabout\dospecialabout} \fi
\ifx\from \undefined\else \let\normalmathfrom \from
\unexpanded\def\from {\mathortext\normalmathfrom \dospecialfrom } \fi
\ifx\over \undefined\else \let\normalmathover \over
\unexpanded\def\over {\mathortext\normalmathover \dospecialabout} \fi
\fi
(added \unexpanded). This is certainly useful for \in and \over, maybe not
so much for the other three.

[NTG-context] Value of Metapost variable as a label
Hello,
First of all, Mojca thanks very much for the update about TikZ. (I could not
find an option to reply in Context Garden mailing list).
My new question is the following. I have the following code to generate the
labels for the tick marks:
for i = 0 step 5 until 45:
draw (i,0)*u -- (i,-0.2)*u;
label.bot(decimal(i) ,(i,-0.2)*u);
endfor;
As you can see I use decimal(i) to get the labels (0,5,10,... and so on).
But the font of these numbers is not the same as when I use the btex
label_text etex command, which I have set to palatino. How can I typeset
the value of Metapost variables (such as i in this case), using tex
commands. For example, if I had to typeset (n_{1},n{2},...,n_{100}), how
could I do that.
On page 63 of John Hobby's metapost manual, he talks about how this could be
achieved using TEX.mp. I tried typing \input TEX before \starttext, however,
I get the error I can't find file `TEX;' If I put it within the
\startuseMPgraphic and \stopuseMPgraphic, it still does not work. Do I have
to download this from somewhere or does Context have another solution?
Thanks very much.

Use textext.
