I do all this (and I guess I'm not alone) sometimes. Sometimes more, sometimes less. But since I (and again I guess I'm not alone) ran into the trouble of not understanding my own code when reading it later, let alone the code of colleagues, I tend to lift "sometimes" to "(nearly) always" - for nearly all most of the above cases.
GeneralDepends on who will use my code Pin
