It's a similar *concept*, but in no way is it similar in performance degradation. It is in no way one with a serious enough difference to matter when there are probably more useful bottlenecks to go after, but only *after* you profile and collect data. Premature performance optimisation should be avoided unless there is data already that shows something will make a difference. Otherwise, the beautiful code mantra applies: 1. Correct. 2. Pretty. 3. Fast.
