yes, several times. if it works for you, i just have bad luck. as said:
not my day..
don't know if i'm still out of luck or if it's a general problem
(luatex trunc, context beta 03.05.2008).
there was also some 'hide' missing, but anyway i still get the same
error. code looks ok to me, but i'm no experienced mp programmer. maybe
a luatex/mplib problem with vardef grouping? i'm puzzled.
