There is a similar case. Ruby 3.3 still says "Process::Status#& is deprecated and will be removed in Ruby 3.4", althoug... shugo (Shugo Maeda)

12:21 PM Ruby Feature #22304: Add rb_warn_to_remove_at() for deprecation warnings shown by default

Thank you for the idea. I think the API should keep the version numbers, because the warning message has to tell users the version ("will be removed in Ruby 4.3"), and a year cannot be converted to a version at compile time.

04:50 AM Ruby Feature #22304: Add rb_warn_to_remove_at() for deprecation warnings shown by default

I've created a pull request: https://github.com/ruby/ruby/pull/18904 shugo (Shugo Maeda)

01:42 AM Ruby Feature #22304: Add rb_warn_to_remove_at() for deprecation warnings shown by default

In addition, how about a higher-level macro that takes both versions of the schedule?
```c
rb_warn_scheduled_deprecation(4.2, 4.3, fmt, suggest, ...)
```
Before 4.2 it warns only when `Warning[:deprecated]` is enabled, from 4.2 it warn... shugo (Shugo Maeda)

04:05 AM Ruby Bug #22276 (Assigned): alias in a module falls back to Object even in classes not inheriting from Object

I've added a verbose-mode warning: https://github.com/ruby/ruby/pull/18740 shugo (Shugo Maeda)

03:37 AM Ruby Revision 1c0b1be0 (git): Deprecate the fallback to Object for alias in a module

`alias` and `Module#alias_method` in a module fall back to searching
the method from Object when the module and its ancestors do not have
it. The fallback assumes Object is the root class, which is no longer
true since BasicObject was in... shugo (Shugo Maeda)

05:19 AM Ruby Feature #22309: Allow super in a module method to work if method was called by refinement method super

03:09 AM Ruby Feature #22309: Allow super in a module method to work if method was called by refinement method super

Thank you for working on this. I checked out the PR branch and tested it.
The stack walk can be fooled. It assumes that the frame below the refinement frame, if it has the same `self` and the same method id, is the frame that called `su... shugo (Shugo Maeda)

12:56 AM Ruby Feature #22304 (Open): Add rb_warn_to_remove_at() for deprecation warnings shown by default

Deprecations such as #22205 and #22276 are scheduled in phases: a warning shown only when `Warning[:deprecated]` is enabled, then a warning shown by default, then the removal.
For the first phase, `rb_warn_deprecated_to_remove_at(X.Y,... shugo (Shugo Maeda)
