Hi,
The *next* lmtx upload (one of these days) will have a small extension
to the mp library wrt strings. In order to be more " neutral the string
can be bound by STX/EOT characters (enabled by default). In addition to
that there is also an option to set the catcode regime. The combination
of these permits passing and processing strings as-they-are. Just in
case the Gerbens among us need it.

==================== example =====================
\startTEXpage
\def\foo{x}
\framed{\startMPcode
interim catcoderegime := vrbcatcoderegime ;
draw textext("stream $\string\foo$") withcolor "darkred" ;
\stopMPcode}
\framed{\startMPcode
draw textext("stream $\foo$") withcolor "darkblue" ;
\stopMPcode}
\startlmtxmode
% here the string starts with ascii code 2 (STX) and ends with
% ascii code 3 (EOT) ... visibility depends on the editor and
% font used; these are normally not used and therefore nice
% alternative string capsules
\framed{\startMPcode
interim catcoderegime := vrbcatcoderegime ;
draw textext(stream $\string\foo$) withcolor "darkgreen" ;
\stopMPcode}
\framed{\startMPcode
draw textext(stream $\foo$) withcolor "darkyellow" ;
\stopMPcode}
\stoplmtxmode
\stopTEXpage
