Comments are not passed through the AST, but somehow they make it from
the input file to the output file. It looks like in
Camlp4/Printers/OCaml.ml there is a hook into the tokenizer to keep
track of comments as they are tokenized (search for CommentFilter).
Maybe there is some way to inject comments (at particular locations)?
Possibly by calling Gram.lex_string and/or Gram.filter? A hack, no
doubt.
