Thanks for the link. Best as I can tell from the ClojureScript, this is in reference to a refactoring that would cross layer boundaries. Like taking the methods

    findItems(db)
    findWidgets(db)

and refactoring to

    findAnything(db, items_tablename)
    findAnything(db, widgets_tablename)

So the repetition is good because it's a data access layer and you shouldn't know the storage details, not because repetition is always good.
