You're looking at a markdown-formatted docstring. Note that it's enclosed in """, similar to Python except that it precedes the method definition. Within the markdown formatting, you can use ``` fences to format code examples.

GitHub's coloring here doesn't quite make it as obvious as it can be. Here's how it renders at the REPL with the help system: http://imgur.com/rlAnpSK
