And along that line, recent wisdom is that it's better to move things *out* of classes (and structs) if they don't need access to private members. (Sorry, I wanted to include a link for this, but I couldn't find the article -- the title eludes me and google isn't turning up anything useful.) Class and struct APIs should be as minimal as possible -- just enough to do what needs to be done and no more, and the rest of the syntactic sugar (that makes it more palatable to your users) belongs outside as optional convenience functions.
Maybe you are thinking of the "Prefer non-member non-friend functions to member functions" rule from Herb Sutter's "Effective C++" books?
