Wow! "experimental metapost version two"
(does this mean that we get to play with precision?)

\startQUESTION
The following minimal example yields an error:
\starttext
\startMPcode
input circle ;
\stopMPcode
\stoptext
where circle.mp contains a btex...etex sequence:
draw fullcircle scaled 1cm ;
label (btex 1 cm etex , (0,0)) ;
The "input circle ;" will work if I comment-out or remove label ;
The minimal example will work, of course, if the mp code is
in my tex file.
The error message is:
mplib : loading 'metafun.mp' (experimental metapost version two)
! mp terminal: (circle.mp
circle.mp
circle.mpx
! Unable to make mpx file.
l.2 label (btex

..

hm, looks like I have to intercept the inputs in order to turn the btex
... into textexts (which happens with the main file)
what I actually need for this is a reader hook (just like we have a
finder hook); I could use the finder hook to make a temporary file, but
I wonder if that makes sense so let's first check if we can get a reader
hook
(remind me in a few weeks anyway and use textext instead of btex/etex
for the moment)
