+
+        There was an apparent improvement in the distill params
+        methodology used in exec_driver_sql which allows raw tuples to
+        pass through.  In 1.4 there seems to be a _distill_cursor_params()
+        function that says it can handle this kind of parameter, but it isn't
+        used and when I tried to substitute it in for exec_driver_sql(),
+        things still fail.
+
+        In any case, add coverage here for the use case of passing
+        direct tuple params to exec_driver_sql including as the first
+        param, to note that it isn't mis-interpreted the way it is
+        in 1.x.
