      Currently, the semantics of $unset is ambiguous when arrays are involved. For instance, the following returns

      {a:[]}

      start:

      { a : [] }

      update: { $unset :

      { "a.0" : 1 }

      }

      But the following returns

      {a:[null]}

      start:

      { a : ['abc'] }

      update: { $unset :

      { "a.0" : 1 }

      }

      We'd like the $unset semantics to be that of setting a position to null, when the target of the unset is an array's element.
