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)]

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
