To use variable accessors, or not to use, that's my question :)

[quote author="bullspit" date="1239216366"]I noticed most of CI code doesn't protect class variables and access with var accessors, is that the recommended way to go with CI?

Thanks[/quote]

It is completely up to you. As in any other cases. I personally prefer to incapsulate class functionality and leave space for improvement and extension. If you use it you'll be surprised how useful it might appear when refactoring your code.
