 # Tests for the -df command line option, which adds debug logging for

-# TODO: Implementation
+.MAKEFLAGS: -df

+# XXX: In the debug log, the "new loop 2" appears out of context.
+# There should be a "begin loop 1" before, and all these messages should
+# contain line number information.
+#
+# XXX: The "loop body" should print the nesting level as well.
+#
+# XXX: It is hard to extract any information from the debug log since
+# the "begin" and "end" events are not balanced and the nesting level
+# is not printed consistently.  It would also be helpful to mention the
+# actual substitutions, such as "For 1: outer=b".
