Or prevent expansion of \over
label.bot(textext("$1\noexpand\over" & decimal k & "$"), (10,0)) ;
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.
