Major problem with Scilab 6.0.0 or Scilab 6.0.1 :

s = struct("a", list(1,2), "b", list(3));

--> s

  b: list


--> typeof(s.a)
 ans  =
 list
// OK 


--> typeof(s.b)
 ans  =
 list
// OK 


--> typeof(getfield("a", s))
 ans  =
 list
// OK 


--> typeof(getfield("b", s))
 ans  =
 list
// OK 


--> typeof(s("a"))
 ans  =
 list
// OK
