how about adding

let @## = @# ;

to mp-tool.mp (you need to remake the context format in mkiv or the metafun format in mkii)

seems to work

Works in mkiv, but in mkii I get an error with

\starttext
\startMPcode
   vardef foo = draw (0mm,0mm)--(10mm,10mm); enddef;
   foo;

   vardef x...@# = (@#,@#) enddef ;
   draw xy0mm -- xy10mm;
\stopMPcode
\stoptext

! Illegal parameter number in definition of \...@mpg@@@.
<to be read again>

hm, weird. did you remake the metafun format?

I did. Just to verify, I created an mp file

beginfig(1) ;
vardef x...@## = (@##,@##) enddef ;
    draw xy0mm -- xy10mm;
endfig;
end;

and ran mpost -progname=metafun test.mp which gives me the correct output, so @## is defined. I am using 2009.09.18. I'll try later with the latest beta.
