      Was just talking about #991 with Dwight and noticed that you can't workaround by doing $push / $pop to the same field on the same update, for example:

      > db.test.drop();
      false
      > db.test.save(

      { mylist: [1,2] }

      );
      > db.test.update( {}, { $push:

      { mylist: 3 }

      , $pop:

      { mylist: -1 }

      } );
      Field name duplication not allowed with modifiers

      Would be nice if this was permitted.
