At this point it would seem beneficial to differentiate between a bug and a logic error. Roughly, a bug would seem to be code that falls into one of two categories: * code that doesn't do what the developer intended * code that generates errors A logic error would be found in code that does exactly what the developer intended, but what the developer intended is the wrong thing to do. This could be expanded to include the inability of CBO to properly identify a usage pattern. just my opinion.
