+//   #define(able) assert() behavior for debugging/testing. It may be
+//   a suitable location for other furry woodland creatures as well.
+//
+// Notes:
+//   If you find yourself compiling small test progs as much as I
+//   do, you can move this file to a location your compiler(s)
+//   will find, and possibly add more cheap debugging stuff...
