RE: [sv-ec] streaming operator and const members of class

It is an assignment to a const, so I would expect an error.

Subject: [sv-ec] streaming operator and const members of class

LRM does not say explicitly how should tool behave if there is a streaming operator used to unpack stream into a class which has const fields.
Const field cannot be changed - so in such situation tool should trigger an error?
On the other hand this kind of operation is not typical assignment to const which is not allowed.

Any opinions - how should below code behave

CODE:

class A;
    const byte a=1;
    const byte b;
    byte c;
    function new;
        b=2;
    endfunction
endclass

module top;
A a=new;
initial begin
    {>>{a}} = 24'h020304;
end
endmodule
