 ### [Call for Testing](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
 An important step for RFC implementation is for people to experiment with the
 implementation and give feedback, especially before stabilization.  The following
 RFCs would benefit from user testing before moving forward:
 
-<!-- Calls for Testing go here, use this format:
-    * [<RFC Topic>](<RFC URL>)
-        * [Tracking Issue](<Tracking Issue URL>)
-        * [Testing steps](<Testing Steps URL>)
--->
-<!-- or if there are no new or updated RFCs this week, use: * *No New or Updated RFCs were created this week.* -->
-<!-- Remember to remove the `call-for-testing` label from the RFC so that the maintainer can signal for testers again, if desired. -->
+* *No RFCs issued a call for testing this week.*
 
 If you are a feature implementer and would like your RFC to appear on the above list, add the new `call-for-testing`
 label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature
