index type.

Hi,

According to LRM P1800.2005,section 5.9.7 In general, associative arrays
that specify an index of any type have the following properties:
 -Declared indices must have the equality operator defined for its
  type to be legal. This includes all of the dynamically sized types
  as legal index types.
 
 -An index expression that is or contains X or Z in any of its elements
is invalid.

So according to above section is the following testcase is valid?

module tmp;

typedef enum reg[3:0]{A = 4'b001x,D = 4'b0010,B,C[6:0]} my_enum; reg
[3:0] l1[my_enum];

initial
begin
l1[A] = 4'b1100;
end
endmodule

As all the simulator passing this one.

Thanks,
Dhiraj
