At present, the two consecutive UNM do not seem to be eliminated:

a = - -"5"

        1       [1]     LOADK           0 -2    ; "5"
        2       [1]     UNM             0 0
        3       [1]     UNM             0 0
        4       [1]     SETGLOBAL       0 -1    ; a
        5       [1]     RETURN          0 1


Try: a = - -5

Coercion is not optimized at compile-time, I think.
