    <![CDATA[
    There should be exactly 1 space after the function keyword and 1 space on each side of the use keyword.  Closures should use the Kernighan/Ritchie Brace style and other single-line functions should use the BSD/Allman style.  Multi-line function declarations should have the parameter lists indented one level with the closing parenthesis on a newline followed by a single space and the opening brace of the function.
