    I have barely any Racket experience, but this sounds really good to me:

    "My favorite part of Racket is how it supports a certain development style of evolving scripts into programs […] I transition from "no code" to "working code" to "robust code" to "re-usable code", the program is almost always runnable."

    Here is the same project, done in PHP in less then 5 minutes...

      $split_by_whitespace = explode(file_get_contents('exaample.txt')," ");
  $circular = array();
  for ($i=0;$i<count($split_by_whitespace);$i++) {
	  array_push(array_shift($split_by_whitespace));
	  $circular[]=$split_by_whitespace;	  
  }
  sort($circular);
  print_f($circular);
    While I am sure there a lot of interesting use cases for Racket, but when it comes to processing array data, I'll take PHP everytime.

    I really like Racket, but I wish there was more community and support around it outside the educational world.

    Great to see Northeastern's computer science program represented on Hacker News

    Does he use the symbol for lambda without saying how to type it or whether there's an ascii equivalent like "lambda"?
