Alternate Constructors

  Constructor messages other than new() can be declared using the
  CONSTRUCTOR clause of the METHOD (declaration) command, as
  follows:

    METHOD <methodName> CONSTRUCTOR

  or:

    METHOD <methodName> CTOR           // abbreviated form

  Each constructor message declared in this way must have a corresponding
  initializer method defined in that class. The initializer method should
  have the same name as the constructor message.

  When such a constructor message is sent to a class, it invokes a
  predefined system method (called altNew) which creates a new object
  and sends the appropriate initializer message to the new object.
