> Streaming expressions currently supports an {{update(...)}} decorator
> function for wrapping another stream and treating each Tuple from the inner
> stream as a document to be added to an index.
> I've implemented an analogous subclass of the {{UpdateStream}} called
> {{DeleteStream}} that uses the tuples from the inner stream to identify the
> uniqueKeys of documents that should be deleted.
