  3. Let _entries_ be the List that is _M_.[[WeakMapData]].
  4. If CanBeHeldWeakly(_key_) is *false*, return *undefined*.
  5. For each Record {[[Key]], [[Value]]} _p_ of _entries_, do
    a. If _p_.[[Key]] is not empty and SameValue(_p_.[[Key]], _key_) is *true*,
      return _p_.[[Value]].
  6. Return *undefined*.
