One of the Python parsing tools is PyGgy by Tim Newsham. Linked from his home page was this concise definition of a contractor:

/* from ali rahimi */
struct ComputerContractor
{
    double    salary;
    long      lunches;
    float     jobs;
    char      unstable;
    void      work;
    int       hiring_him_again;
    const     pain_in_the_arse;
    unsigned  agreement;
    short     fuse;
    volatile  personality;
    static    progress;
};  /* and there are no unions in sight */

Brilliant.
