I have encountered a problem when using \fac, \eqalign and
\usemodule[newmat] at the same time. I like the newmat module since it
gives me the \QED command, but when using \frac inside \eqalign I get
an error I cannot understand.
\usemodule[newmat]
% This works fine.
\starttext
\startformula
\frac12=\frac24
\stopformula
% Uncomment to get error.
%\startformula
%\eqalign{\frac12={}&\frac24\cr}
%\stopformula
% This works fine.
\startformula
\eqalign{{1\over2}={}&{2\over4}\cr}
\stopformula
\stoptext
The log file is attached.

Alle spørgsmål er lige dumme.
Og spørgsmålet "Kan ænder flyve?" er ikke dumt.
