Hara theorem
WebGoal Theorem 1 Every countable model of PA has a pointwise definable end-extension. The same method applies in set theory. Goal Theorem 2 Every countable model of ZF has a pointwise definable end-extension. Can achieve V = L in the extension, or any other theory, if true in an inner model of V = HOD.
