Then the amount of passes not so important speaks that, and it would be quite good to allow to describe a variable in any place. I think that the author starts with a false premise. A principle "at first describe, and then use" it is used first of all for convenience of reading of the program as the person reads from top to down and to wind the code there-here it is banal inconveniently. I personally adhere to that point of view that the variable should be described as much as possible close to a place of first usage (is better - in the same construction). Still variable on a maximum should be invariable, but it does not concern any more a subject.
