-  <!-- TODO(rsc): add GOEXPERIMENT=loopvar -->
+  Go 1.21 includes a preview of a language change we are considering for a future version of Go:
+  making for loop variables per-iteration instead of per-loop, to avoid accidental sharing bugs.
+  For details about how to try that language change, see <a href="https://go.dev/wiki/LoopvarExperiment">the LoopvarExperiment wiki page</a>.
