RE: [sv-ec] null compabiilty

This is illegal because

 

1.	The value set for int is 2-state 32-bit integral values, and
2.	There is no implicit or explicit cast defined between the
special value null and an integral value.

Is it explicitly said in LRM how null should behave in below case -
should it be legal usage or not. (I cannot find such description nor
mantis item) :

 

module top;
    int x;
    initial if(x==null) $display("false");    
    initial x = null;
endmodule
