 Then The default constructor will be: >
 
-	def new(this.name, this.age, this.gender)
+	def new(this.name = void, this.age = void, this.gender = void)
 	enddef
 
 All object members will be used, also private access ones.
 
+The "= void" default values make the arguments optional.  Thus you can also
+call `new()` without any arguments.  Since "void" isn't an actual value, no
+assignment will happen and the default value for the object members will be
+used.  This is a more useful example, with default values: >
+
+	class TextPosition
+	   this.lnum: number = 1
+	   this.col: number = 1
+	endclass
+
+If you want the constructor to have mandatory arguments, you need to write it
+yourself.  For example, if for the AutoNew class above you insist on getting
+the name, you can define the constructor like this: >
+
+	def new(this.name, this.age = void, this.gender = void)
+	enddef
+
