-    Users of the language are advised to use that form when a do-while
-    loop would have been appropriate.
+    A syntax alternative to the one proposed in the PEP was found for
+    a basic do-while loop but it gained little support because the
+    condition was at the top:
+
+        do ... while <cond>:
+            <loop body>
+
+    Users of the language are advised to use the while-True form with
+    an inner if-break when a do-while loop would have been appropriate.
