Object construction

Objects can also be created with an object construction expression that has the syntax T(fieldA: valueA, fieldB: valueB, …) where T is an object type or a ref object type:

type
  Student = object
    name: string
    age: int
  PStudent = ref Student
var a1 = Student(name: "Anton", age: 5)
var a2 = PStudent(name: "Anton", age: 5)
# this also works directly:
var a3 = (ref Student)(name: "Anton", age: 5)
# not all fields need to be mentioned, and they can be mentioned out of order:
var a4 = Student(age: 5)

Note that, unlike tuples, objects require the field names along with their values. For a ref object type system.new is invoked implicitly.
