我经常发现这个

// fix it!

// long live COM'n'Roll
public enum StatusCode
{
        //success codes
        S_OK                                            = 1,
        S_NONE                                          = 2,
        S_SQL_OPERATIONS_LISTS_EMPTY                    = 3,

        //error codes
        E_NO_MATCHING_END_FOUND                         = -1,
        E_SEQUENCE_NUMBER_NOT_FOUND_AT_BEGINNING        = -2,
        E_SEQUENCE_NUMBER_NOT_FOUND_AT_END              = -3,
        E_FORWARD_AND_BACKWARD_OPS_COUNT_DO_NOT_MATCH   = -4,
        E_FORWARD_AND_BACKWARD_IDS_DO_NOT_MATCH         = -5,
        E_IDS_DO_NOT_MATCH                              = -6
}

多年前，我遇到了这样一个问题:

/***************************************************************************/
/*  deep wizardry. do not touch.                                           */
/*                                                                         */
/*  no seriously.  XXXXXX I'm looking at you. If you screw with this again */
/*  I will kill you with my swingline stapler.                             */
/*                                                                         */
/* ...                                                                     */

然后描述了一个特别复杂的算法。
