mongorestore silently ignores documents with invalid field names starting with $

      In MongoDB 2.0.7 it is possible to update() a document and set an invalid field name starting with $:

      > db.test.insert({_id: "foo"})
      > db.test.update({_id: "foo"}, {$set: {$set: "bar"}})
      > db.test.find({_id: "foo"})
      

      If you mongodump and then mongorestore this database, documents with invalid field names are silently ignored (even with `mongorestore -vvvvv`).

      In MongoDB 2.2.0rc2 the attempt to update() does throw an exception:

      Modified field name may not start with $
      

      .. but mongorestore still does not report any errors for skipped documents.
