ELENA does not support adding a field at run-time but it can be simulated with the help of a mix-in.
ELENA 3.x1
<lang elena>#import extensions.
 
class Extender :: BaseExtender
{
object prop(foo) :: prop(theField).
constructor new : anObject
Line 346:
anObject := Extender new:anObject.
 
anObject set &foo := "bar".
