/**
 * The only function of this statement is to return $poll_id if it's set. Which
 * snippet would you use and why?
 *
 * I (@jrtashjian) prefer and wrote snippet 1. I like how contained the
 * function is, and the fact I'm only calling the post() function once.
 *
 * Each snippet works correctly, this is just preference. I find it redundant
 * to call the post() function more than once (as shown in snippet 3). I also
 * find it unnecessary to create a variable ($poll_id) to store the result of
 * function post() when I'll only be using it for the if statement.
 *
 * Let me know on Twitter, @jrtashjian.
