I would like to put some math in metapost pictures. For the moment I am using textext for the typesetting in my metapost

picture pic will be placed in the metapost figure.
Simple math like $p=2$ works fine, but the system chokes on something like the
following matrix:
$\pmatrix{p_{0|0}\cr}$ (it does fine in ConTeXt itself).
The error is: ! Only one # is allowed per tab.

Perhaps I am too optimistic about textext's possibilities. But how can I
accomplish the placement of these and more elaborate formulae in metapost
pictures using ConTeXt? It is of the essence for a series of Powerpoint slides
I am preparing, wheein these formulae must be placed as individual pictures.
you can patch pmatrix:
\unexpanded\def\pmatrix#1%
{\left(\matrix{#1}\right)}
(i'll make the lot unexpandable)
btw, for large chunks you can consider using setups
\startsetups lots-of-math
\stopsetups
... \textext("\setup[lots-of-math]")
