| 54 | +## [Call for Testing](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing) |
| 55 | +An important step for RFC implementation is for people to experiment with the |
| 56 | +implementation and give feedback, especially before stabilization. The following |
| 57 | +RFCs would benefit from user testing before moving forward: |
| 58 | + |
| 59 | +<!-- Calls for Testing go here, use this format: |
| 60 | + * [<RFC Topic>](<RFC URL>) |
| 61 | + * [Tracking Issue](<Tracking Issue URL>) |
| 62 | + * [Testing steps](<Testing Steps URL>) |
| 63 | +--> |
| 64 | +<!-- or if there are no new or updated RFCs this week, use: * *No New or Updated RFCs were created this week.* --> |
| 65 | +<!-- Remember to remove the `call-for-testing` label from the RFC so that the maintainer can signal for testers again, if desired. --> |
| 66 | + |
| 67 | +If you are a feature implementer and would like your RFC to appear on the above list, add the new `call-for-testing` |
| 68 | +label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature |
| 69 | +need testing. |
| 70 | + |
| 71 | +## Call for Participation; projects and speakers |
