  WeakMap.prototype.delete ( _key_ )
  3. Let _entries_ be the List that is _M_.[[WeakMapData]].
  4. If CanBeHeldWeakly(_key_) is *false*, return *false*.
  5. For each Record {[[Key]], [[Value]]} _p_ of _entries_, do
    a. If _p_.[[Key]] is not ~empty~ and SameValue(_p_.[[Key]], _key_) is
      *true*, then
      i. Set _p_.[[Key]] to ~empty~.
      ii. Set _p_.[[Value]] to ~empty~.
      iii. Return *true*.
