Hi.  With the help of several documents, including "TeX as a
Presentation Tool" (art-pres.pdf) I have configured my teTeX
installation so that it's ready for inline MetaPost in ConTeXt.  

I made a little yellow circle.  (Whoo!!!)  But when I tried to add a
label I noticed that the mp source was getting broken:

    \setupcolors[state=start]
    \def\myMPFig%
    	    {\startreusableMPgraphic{}
    	    input mp-tool;
    	    fill fullcircle scaled (1in) withcolor (1, 1, 0);
    	    label.rt(btex first inline etex, (.5in, .25in));
    	    \stopreusableMPgraphic
    	    \reuseMPgraphic{}}

    \starttext
    hi
    \myMPFig
    bye
    \stoptext

... resulting in mpgraph.mp:

    mpgraph:=1;
    beginfig(1);
    input mp-tool;
    fill fullcircle scaled (1in) withcolor (1, 1, 0);
    label.rt(btex first inline etex;
    , (.5in, .25in));
    endfig;
    end.

... which doesn't work, of course.  Why is the semicolon getting added
before the comma?  Are there constraints on how to write mp code
inside of context?
