ah ... the alignment lookahead problem, i think we can safely patch
\mathematics to catch lookahead as well as make frac more robust for
unwanted expansion
\usemodule[newmat]
\unexpanded\def\frac#1#2{\mathematics{\genfrac{}{}{}\donothing{#1}{#2}}}
\def\mathematics#1{\relax\ifmmode#1\else$#1$\fi}
\starttext
\placeformula
\startformula
\eqalign{\frac{1}{2}}
\stopformula
\stoptext
