11:33 AM Ruby Revision 611bb146 (git): [Feature #22304] Add rb_warn_to_remove_at and rb_warn_scheduled_deprecation

rb_warn_deprecated_to_remove_at warns only when Warning[:deprecated]
is enabled, so a deprecation scheduled to warn by default in a later
version needed a hand-written rb_warn and a separate commit to switch.
rb_warn_to_remove_at emits ... 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.
A major ver... shugo (Shugo Maeda)

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)
