Dscanner looks like a good starting point for a code formatting 
tool (like gofmt). However, there seems to be a tradeoff with 
performance involved. For compilation you want a fast lexer and 
parser. For formatting you need to preserve comments, though.

For example, convert this from source to AST to source without 
losing the comments:

void /*hello*/ /*world*/ main () { }
