[sv-bc] !, && and || operators allowed for virtual interface or event or chandle variables

Hi,

!, && and || operators are allowed for class handle variable as null can be 
assigned to any class handle variable.

And null can also be assigned to any virtual interface or event or chandle variable
So  !, && and || operators should be allowed for these variables too.
So if we have a testcase -
    I1 i1();
    virtual i1 vi1 = null;
    virtual i1 vi3 = null;
    chandle d, a   ;
    event e1, e2 = null;

    initial begin
        if (vi3 || vi1)  //|| operaor is used with virtual interface variable
	begin
	end 
        if( d && a)  //&& operator is used with chandle variable
	begin
        end 
        if(!e1) // ! operator is used with event varaible
        begin
        end
    end
endmodule

interface I1;
endinterface


Is there any issue for these cases?

Thanks and regards,
Moumita
