In function `numItems()` by the definition of `RLPItem` it is clear the the value of `currPtr` can never exceed `endPtr` and the while loop on line 234 would stop when `currPtr` and `endPtr` are equal, hence instead of `currPtr < endPtr` we can use `CurrPtr != endPtr` as each not equal comparison costs 3 less gas (negligible for short `RLPItem`, this exhibit is just here for completeness) than less than comparison
