+//       should you at all?  Most stuff is better in specific tests, or in

+//       shell.js?  Our goal is to unify these two files for readability, and
+//       the plan is to empty out this file into that one over time.  Third,
+//       supposing you must add to this file, please add it to this IIFE for
+//       better modularity/resilience against tests that must do particularly
+//       bizarre things that might break the harness.
