I'm aware that ruby class files should generally be quite small, but sometimes I find logic in classes that (a) don't really warrant their own file, but (b) would be more readable if I could group them somehow.

For example, in certain classes I may have (let's say) 10 methods which determine paths. At the moment, I tend to just throw some a few lines of decorative "### PATHS ###" type comments around them to distinguish them from the rest of the group. I'm wondering if theres a better way(?)

Am I right in thinking implementing subclasses/modules within a class just to improve readability is a little excessive, or do other folks do this? Any other thoughts appreciated.
