+It may look unusual, but it has advantages:
+
+* It allows one to swap out the higher-level package ``foo`` for something
+  else that provides the similar API. An example would be swapping out
+  one Database for another (e.g. graduating from SQLite to PostgreSQL).
+
+* Looks more neat in cases where a large number of objects get imported from
+  that package.
+
+* Adding/removing imported objects from the package is quicker and results
+  in simpler diffs.
