variable is incorrectly marked as global in generator

[Pangoraw]

maybe related: i is incorrectly marked as global here:

triuvec(x) = [x[i,j] for j=1:size(x,2) for i=1:j-1]

(Since this is a bug in our highlighting extension, not the expression explorer, you need to also define i = 123 in another cell to reproduce.)

Maybe this is impossible, because it needs to traverse backwards?
