Your comment is probably related to the comment of making the `PageSizeSet` class private. Hmm, I did try that out though and compiled locally on Linux.... maybe I messed up somewhere. Leave it public then.

Otherwise I am a bit confused how this statement relates to the request to move the code comment to the .hpp file.
