  New Revision: 16106

  Modified files:
    trunk/ChangeLog
    trunk/enumerator.c

  Log:
    * enumerator.c: Resolve the method every time an enumeration
      method is run, not once when the enumerator is initialized as it
      was before, so that method_missing() and method (re)definition
      afterwards are both in effect; pointed out in: [ruby-core:16441]
