- @kddnewton There is already a PR with both parse.y (from @nobu) and Prism changes: https://github.com/ruby/ruby/pull/11065
I'd be happy to rebase, update that branch and merge any other changes you think are important for Prism.

04:42 PM Ruby Feature #13683: Add strict Enumerable#single
- @Dan0042 If the proposed method isn't going to raise an exception, then how would one disambiguate between a `nil` result because the collection has a single entry which is `nil` and a `nil` result since the collection has (for example) ...

02:52 PM Ruby Bug #21654: Set#new calls extra methods compared to previous versions
- IMO, ranges should behave the same when `end == Float::INFINITY` and when `end == nil`. They are both practically endless ranges, but nothing normalizes them so that they always behave the same. Maybe `(1..1/0.0)` should be internally tr...

- There is a configuration file to control which labeled PRs make it into the automated release notes and which ones should be excluded. I can help set that up if it will be helpful.
