Style guide

The Clojure team did not publish an official style guide on their website, but there's a community-driven document available at http://github.com/bbatsov/clojure-style-guide.

Some of the more important rules discussed in the document are:

• For indentation, generally use two spaces.
• In a function definition with defn, place the function name and input parameters on a single line and the body on a new line:

        (defn function1 [input]
        ( ...function calls here... )

• When a parameter does not fit on one line, align it vertically. Use one space:

        (defn function2 []
          (str
              "Hello"
              " and goodbye"))

• Don't put commas between elements in a list.
• Use good taste when coding hash-maps. When you have multiple key/value pairs on the same line, use a comma to separate them.
• Do not put trailing parentheses on their own line (in the function2 example we just saw, the last line closed both the parameters and the function blocks).
• Linux newlines (LF) are...
