Hello,

Is it possible to nest cases in math, like so:

\starttext
\startformula
x=
       \startcases[align={right,left},distance=3pt]
               \NC  a \NC =
                       \startcases[align={right,left},distance=3pt]
                       \NC  1 \NC  \text{case  a1} \NR
                       \NC  2 \NC  \text{case  a2} \NR
                       \stopcases
               \NR
               \NC b \NC =
                       \startcases[align={right,left},distance=3pt]
                       \NC  3 \NC  \text{case  b3}\NR
                       \NC 4  \NC  \text{case  b4}\NR
                       \stopcases
               \NR
       \stopcases
\stopformula
\stoptext

I get an error about a missing $ when I try a nested start/stop-cases.

Thanks,

Matthias
