+=head2 Skip object creation for faster results
+
+DBIx::Class is not built for speed, it's built for convenience and
+ease of use, but sometimes you just need to get the data, and skip the
+fancy objects. Luckily this is also fairly easy using
+C<inflate_result>:
+
+  # Define a class which just returns the results as a hashref:
+  package My::HashRefInflator;
+
+  ## $me is the hashref of cols/data from the immediate resultsource
+  ## $prefetch is a deep hashref of all the data from the prefetched
+  ##   related sources.

+     };
+  }

+  sub inflate_result {
+     my ($self, $source, $me, $prefetch) = @_;
+     return mk_hash($me, $prefetch);

+
+  my $datahashref = $rs->next;
