It seems that \NC in mathalignment is looking ahead for the next \NR, because
when I wrap the matrix
in an explicit brace group it works fine again:
\definemathmatrix
[pmatrix]
[left=\left(,right=\right)]
\starttext
\placeformula
\startformula
\startmathalignment
\NC \sigma_x \NC=
{\startpmatrix
\NC 0 \NC 1 \NR
\NC 1 \NC 0 \NR

\NR[+]
\stopmathalignment

yes. in retrospect giving \NR an argument was a bad idea as we need to
pick it up in advance .. tricky to solve

Dear list,
When I have a mathmatrix inside a mathalignment the numbering using \NR[+] does
not work anymore.
Instead it prints "[+]" on the next line. I guess the definition of \NR from
mathmatrix leaks
outside. Affects both TL2017 and latest beta. MWE is below.
Cheers, Henri
