Hello, Hans and Wolfgang really helped me to create new environments with Metafun. I think Hans continuous development Metafun. So my question is simple: can we optimize this code ?

in what sense ... speed? not much to gain correctness? mayhe use "lightgray" and "darkred" for consistency typography? sure, but more a discussion topic at the ctx meeting
