 ### Short Term
 
+* Think about a way of cleaning up at the end of every test scenario
+  (e.g., to close files or database connections).
+
 * It would be useful to have two combinators that sort a list:
   `unsorted` (deconstructible), and `sorted` (constructible).
   Both would rely on `List.sort`.
