There are a few folks who argue that accessors are bad, objects shouldn't be glorified structs, multiple inheritance is always evil, etc. The main issue I have with statements such as these as they tend to be "holy pronouncements" that some folks take as gospel even though they're just good rules of thumb which should be violated as needed.

The primary benefit I see in considering such pronouncements is thinking about why they're beneficial, something you're doing. Accessors can violate encapsulation. Glorified structs are often overkill. Problems with MI are extremely well-documented. Once we understand why a particular practice is good or bad, then we're much better prepared to either adopt or reject a given practice for a given need. No blanket pronouncements for me!
