The new two-colons syntax is valid in the current beta and nightly, and will be available in 1.77.0. The old one-colon syntax is still supported for compatibility reasons. See #12201 |

Oh I see! Sorry. Do you want to keep the other change? |

The stabilization PR of it is #13571. I would recommend adding a comment there for doc improvements. |

There was a problem hiding this comment.
Btw, this is valid; this defines two different cfgs foo and bar, not one foo="bar".
But I agree this isn't the best example.

Going to close this as the PR author of #13571 is aware of the example improvement. Thank you all :) |
