+// corner cases.
+// First: simplepkg itself contains no (exported) functions
+// or methods and so its generated Go package must not import
+// it.
+//
+// Second: even though testpkg imports simplepkg, testpkg's
+// generated Go package ends up not referencing simplepkg and
+// must not import it.
