That is what I wanted to do in the Go frontend, but unfortunately the current frontend interface actually requires me to generate trees for statements. These trees are then immediately gimplified. It's a waste of time and space. (I haven't tried to fix this because there are unfortunately even bigger wastes of space in the Go frontend.) Ian
