Thanks to Glen De Cauwsemaecker for the self-suggestion!

Please submit your suggestions and votes for next week!

Call 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:

  • No calls for testing were issued 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 need testing.

Quote of the Week

There is absolutely no way I can imagine that Option is causing that error. That'd be like turning on the "Hide Taskbar" setting causing your GPU to catch fire.

[...]

If it's not any of those, consider an exorcist because your machine might be haunted.

Daniel Keep on rust-users

Thanks to Hayden Brown for the suggestion!
