I already pointed out that AR's version is wrong. You can't rely on readline returning EOF or errors more than once.

I thought mine was better than JavaFan's because it lead to the elimination of the duplicate "g()", but that turned out to be a mistake (as per my earlier update).

I still prefer mine over JavaFan's, though. Since mine flows from top to bottom, it requires less skipping around to follow the code.
