Comment(by robe):


 My general opinion -- all versions (minus the _ which to us means
 private), should be documented.   The main reason for me is when I scan my
 list of functions -- I look for things that don't have comments and if I
 see those -- I assume its an oversight or a mistake.

 If you see no need to document their existence then you should think twice
 about why you are creating them and if you should have some of those
 arguments as optional.  If marking them optional is not an option, then I
 say get rid of them and force people to type in the extra stuff if they
 get to that level of minutae.  I know Pierre likes to have his ala carte
 full of choices, but sometimes choice is too overwhelming and should be
 saved for a second course.
