Writing Phrases with Code This is my first contest, so please tell me what I can do to improve.

The object of this contest is to write program lines in your language of choice that are both valid code and self-descriptive in English, such as this Golfscript program:

This program outputs 4 twice.


You may use any language features, libraries, #defines, etc. that you want; however, a setup must not be over 10 lines (no, you can't cheat using ; or any such line separator :P).

The program with the most upvotes by midnight on October 1st wins.
Python
# This &quot;program&quot; does nothing and assumes &quot;valid code&quot; means it doesn't throw an error.

You might want to tighten up the rules a bit.
