08:36 AM Ruby Feature #21552: allow String.strip and similar to take a parameter similar to String.delete

I'm not strongly opposed, but this kind of API that use a string to represent a collection of characters feel outdated. It is sometimes convenient, though. mame (Yusuke Endoh)

08:01 AM Ruby Misc #21689: DevMeeting-2025-12-11

* [Bug #21049] Reconsider handling of the numbered parameters and "it" parameter in `Binding#local_variables` (mame)
* An API like `Binding#numbered_parameter_get` was actually requested. I'd like to discuss how to proceed. mame (Yusuke Endoh)

07:57 AM Ruby Bug #21298 (Closed): `ObjectSpace.allocation_class_path` returns inconsistent results depending on `TracePoint` state

https://github.com/ruby/ruby/pull/13232 had been already merged. Thanks! mame (Yusuke Endoh)

07:17 AM Ruby Feature #19430 (Rejected): Contribution wanted: DNS lookup by c-ares library

Since c-ares has a compatibility issue on macOS, a full migration to it seems difficult. And DNS lookup is now interruptible by explicitly using pthread. Therefore, this is closed as not planned. mame (Yusuke Endoh)

06:54 AM Ruby Misc #21154: Document or change Module#autoload?

I'd like to share a simplified example that demonstrates the autoload/require issue.
```ruby
# my_gem.rb
module MyGem
autoload :M, "my_gem/m" # (2)
end
# my_gem/m.rb
module MyGem

09:25 AM Ruby Bug #21715: Miscompilation on x86-64-v2 due to undefined behavior in search_nonascii in string.c

I wonder if the premise that "unaligned word access is feasible on x86" no longer holds in modern contexts?
We are of course aware that unaligned word access is undefined behavior in C. However, it is slightly faster, which is why we ... mame (Yusuke Endoh)

04:54 AM Ruby Feature #21675: Advent of Pattern Matching

We briefly discussed this at the monthly dev meeting. While we haven't reached a consensus on whether the scope of pattern matching should be expanded in general, I would like to share one specific concern that came up during the discuss... mame (Yusuke Endoh)

02:01 PM Ruby Bug #21698: Should simple ArgumentError refer to Object?

Displaying the method owner class was decided in #19117. The fact that it was not displayed for `"wrong number of arguments"` errors was simply a bug due to an oversight.
We were aware at the time of #19117 that this change would be i... mame (Yusuke Endoh)
