I never use accessors to let a class get at its own data.

That's an interesting statement. I actually always use accesors when dealing with attributes to allow for subclasses to override how they wish to deal with an attribute. But, I tend to work either with datastructure-type classes like Tree where the algorithms of the class need to be separated from the datastorage of the class or with templating engines like Excel::Template where a given node doesn't know if it actually has the attribute or not. (Its parent might have the attribute, so it has to ask a separate context object where the attribute actually has a value.)

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
