You must copy the object by hand. The cleanest way is to implement a 
constructor with an optional argument.

' MyClass.class

PUBLIC X AS Integer
PUBLIC Y AS String
PUBLIC Z AS NEW Collection

SUB _new(OPTIONAL hCopy AS MyClass)

  IF hCopy THEN
    X = hCopy.X
    Y = hCopy.Y
    Z = hCopy.Z
  ENDIF

END

Two problems remains:
1) Copying private fields is more complicated.
2) Copying a collection must be done by hand !
