Felix Mish requested an LL(1) version of


factor:
                TOK_ID
                | TOK_ID "\(" parameters "\)"
                | TOK_NUM
                | "\(" expression "\)"
                | TOK_NOT factor
                | TOK_ID "\[" expression "\]"


How about?


factor : TOK_NUM
        | "\(" expression "\)"
        | TOK_NOT factor.
        | TOK_ID factor_tail
factor_tail :
        | "\(" parameters "\)"
        | "\[" expression "\]"
