I've encountered a MetaPost issue, and since many MetaPost users also use ConTeXt (and vice-versa), I am posting this question on both lists. The command
show identity rotated 270 yscaled 0.5;
outputs (0,0,0,1,-0.5,0) as expected, while the command
show identity transformed (0,0,0,1,-0.5,0);
errors with --- ! Missing `)' has been inserted. <to be read again> , l.26 ^^Ishow identity transformed (0,0,0,1, -0.5,0); --- I am using MetaPost 1.504, and the problem seems to be that MetaPost does not like me using the sextuple (0,0,0,1,-0.5,0) directly, but this is the most convenient method for me to describe my transformations. Is this a bug in MetaPost, or am I not allowed to use transformations directly with sextuples? Troy Henderson

It looks like sextuples are no basic datatype. I think that the show is just a way to output the internal representation. Of course it would make sense to have sixtuples (I can even think of a generic n-tuple).

Albrecht, The issue was to be able to define the transform t using its six components. Troy
