The "alias" directive should not affect RE rules at all, other than perhaps removing one if the alias is defined after a RE rule having the same name was defined.
I would hope another use of ALIAS would be to redirect a subsequent SCORE or DESCRIPTION directive to the renamed rule rather than producing a warning for "score for nonexistant rule" or the like.
Perhaps it already does this, I don't know. I throw this out in case it does not.
