All metapost environments expand their arguments, so anything looking for
an optional argument fails. There are workarounds, though
\unexpanded\def\MYMATRIX%
{$\startmathmatrix \NC 1 \NC 1 \NR \NC 1 \NC 1 \NR \stopmathmatrix$}
\starttext
\startMPcode
label.rt(\sometxt{\MYMATRIX}, origin) ;
label.rt(textext ("\MYMATRIX"), (5cm,0)) ;
\stopMPcode
\stoptext
And if you really want it to work, we need to make cetrain things
unexpandable
\unprotect
\def\dodefinemathmatrix[#1]% [#2]%
{\unexpanded\setvalue{\e!start#1}{\dodoubleempty\dostartmathmatrix[#1]}%
\unexpanded\setvalue{\e!stop #1}{\dostopmathmatrix}%
\setupmathmatrix[#1]}% [#2]
\definemathmatrix[matrix]
\definemathmatrix[\v!mathmatrix]
\unexpanded\def\dodomatrixNC
{\gdef\domatrixNC{\endmath&}}
% To avoid errors in expansion
\let\NC\relax
\let\NR\relax
\protect
Now this works
\starttext
\startMPcode
label.rt(\sometxt{$\startmathmatrix \NC 1 \NC 1 \NR \NC 1 \NC 1 \NR
\stopmathmatrix$}, origin) ;
\stopMPcode
\stoptext
Hans, should we add this to strc-ali?
