Unforunately, what you are trying to do here isn't that easy.
If you just skip the comments during parsing, like you are doing currently, the comments will be lost when auto-formatting code.
And that would be a bad thing.

All the comments must be saved during parsing, so that they can be re-inserted when printing the ast.
That makes all this much mor cumbersome, which is why I haven't bothered to implement comments at every single possible location.
