The initial pretty printer approach consisted of going to a scope and then printing things in that scope as it walked the structure, but this approach doesn't seem to work well because of comments, as it depends too much on how the parsing was done and the comments found (and javacc just spits them out and the parser tries to put them in good places, but this is often not what happens) So, a different approach will be tested: Instead of doing everything in a single pass, we'll traverse the structure once to create a new (flat) structure, in a 2nd step that structure will be filled with comments and in a final step, that intermediary structure will be actually written. This will also enable the parsing to be simpler (and faster) as it'll not have to move comments around to try to find a suitable position.
