Note that the first- and second-person reflexives are generally not needed in the parser. (We define them here anyway, because they're useful for message generation.) The third-person reflexive pronouns have distinct meanings in input from the corresponding ordinary pronouns, in that they refer to noun phrases within the same command rather than in earlier exchanges. In contrast, the second-person pronouns have the same meaning in ordinary and reflexive forms, at least within the confines of the IF parser: EXAMINE ME and EXAMINE MYSELF mean the same thing in all typical IF command syntax.
