[sv-bc] Unpacked subroutine arguments can't have default values?

According to 12.4.3, "To handle common cases or allow for unused
arguments, SystemVerilog allows a subroutine declaration to specify a
default value for each singular argument."

 

So, the following is not legal?

 

      typedef int T [255];

 

      function automatic foo ( T in1, in2 = '{default:0} ) ;

          foreach (foo[i]) foo[i] = in1[i] + in2[i];

      endfunction : foo
