04:23 PM Ruby Feature #12282: Hash#dig! for repeated applications of Hash#fetch

I'll allow myself to copy-paste my reasoning from the related ticket #14602:
Just a bit of "design space" analysis:
1. I think `dig!` is unusual for core Ruby. A lot of Rubyists are used that in Rails pairs like `find_by`/`find_by!... zverok (Victor Shepelev)

05:50 AM Ruby Feature #21386: Introduce `Enumerable#join_map`

Just a thought: shouldn't we add `#join` to `Enumerator::Lazy`? It wouldn't solve "logical repetitiveness" of the pattern, but might be a good _and_ idiomatic way to optimize the pattern when necessary.
(Lazy enumerators are underused... zverok (Victor Shepelev)

02:39 PM Ruby Feature #21435: Kernel#then_try as a conditional #then

@Alexander.Senko I don't think my opinion weights much here, but here it is, nevertheless.
When writing in "chaining" style (which I know is not everybody's favorite), "do this transformation/next step conditionally" is indeed a frequ... zverok (Victor Shepelev)

04:42 PM Ruby Feature #21387: Proposal to add Data#[]

> However, I'm still curious why I've come up with this `#[]` idea.

I am not sure about this argument. The "can be initialized with keyword arguments" and "can be converted to Hash" are probably the most common features among all ... zverok (Victor Shepelev)

07:16 AM Ruby Feature #21387: Proposal to add Data#[]

The design goal of `Data` was to be as close to "just a simple atomic object" as possible and convenient. It is a "value object," not a "container". `#[]` is closer to a container protocol and starts to erode the design.
For a partic... zverok (Victor Shepelev)

06:05 AM Ruby Feature #21264: Extract Date library from Ruby repo in the future

> I think an important question is whether the simplified Date should be ::Date, or something like ::Time::Date. One issue with making the simplified version ::Date is it opens up backwards compatibility issues for code that uses feature... zverok (Victor Shepelev)

03:51 PM Ruby Feature #21264: Extract Date library from Ruby repo in the future

Is it possible to, on the contrary, make Date a core class? Rails, and many other non-Rails codebases I saw, implicitly consider it as such (while kind-of ignoring DateTime, or considering it the "main" time-representing class even when ... zverok (Victor Shepelev)

03:18 PM Ruby Feature #20953: Array#fetch_values vs #values_at protocols

> What's the expected behavior of:
For `..42` versions, I believe that `values_at` behavior gives enough affordance:
```ruby
[1, 2, 3].values_at(..6)
#=> [1, 2, 3, nil, nil, nil, nil]
```
So, I suppose:
```ruby
[1, 2, 3].fetch_... zverok (Victor Shepelev)

08:23 AM Ruby Bug #21030: Bug: #step with Range<ActiveSupport::Duration> behavior broken on Ruby 3.4.1

Confirmed, looking into it. zverok (Victor Shepelev)

08:20 AM Ruby Bug #21026: `def __FILE__.a; end` should be a syntax error

As far as I understand (though it is an intuitive understanding, not backed by looking into particular implementation), `__FILE__` and `__LINE__` are handled at the parsing stage, behaving in (almost) all situations like there was just a... zverok (Victor Shepelev)
