It doesn't seem sensible to have this comment change due to the extraction of 'SexpDresser'. The tool people expect to be using is reek, and changing the keyword would meen people have to go over their entire body of source code to change this. If some other tool uses SexpDresser, that tool will need to have its own special comment format, not related to reek.

As I understand it, the main point of extracting part of reek was to have the decorated Sexp classes that provide handy methods. In that light, as I have mentioned before, I don't think it's a good idea to include the configuration system and the SourceLocator in the extracted code.

In my view, it would make much more sense to extract just the part that is now called TreeDresser, plus the Sexp extension modules it needs.
