Dear all,

is it possible to pass data from MetaPost back to TeX? This would be similar in 
spirit to, say, the MetaPost variable BodyFontSize that contains data from the 
TeX surrounding. Just the other way round.

maybe future mlib versions will provide something like that (writing something from mp to a lua table); currently you have to use a file or interpret the log (use show to print out values).
