-      Removed because the seal function no longer works on JS 1.8 arrays,
-      instead returning an error. The sealing is meant to prevent map
-      functions from modifying the same document that is passed to other map
-      functions. However, only map functions in the same design document are
-      run together, so we have a reasonable expectation they can trust each
-      other. Any map fun that can't be trusted can be placed in its own
-      design document, and it cannot affect other map functions.
