[Newbies] shadowed

[Casey Ransberger]

And to be clear, that means the temporary variable is getting used where the programmer probably thought the instance variable was being used. This is a common source of bugs, so it's usually best to avoid naming collisions between temps and ivars, and that's why the system is warning you about it.

It's a very thoughtful system:)
