lexer.ads

compilation abandoned
gnatmake: "lexer.ads" compilation error

package Lexer is

        keyword_list : constant array (Natural range <>) of St :=
        [
                +"xor"
                [;


end Lexer;

The code is erroneous, but GNAT should give an appropriate message instead of
erroring out.

Missing guard in the parser indeed.
