09:37 PM Ruby Feature #19315: Lazy substrings in CRuby

Yes I think adding `RSTRING_RAW_PTR()` is a good way, I would just suggest another name: `RSTRING_START()`.
Actually now I see this name was already proposed in https://bugs.ruby-lang.org/issues/19315#note-13.
Why I think `RSTRING_ST... Eregon (Benoit Daloze)

09:18 PM Ruby Bug #21640: Core Pathname is missing 3 methods / is partially-defined

Right, `Dir.glob('**/*', flags: File::FNM_DOTMATCH) { ... }` seems a good replacement nowadays, though people might not know about `FNM_DOTMATCH`.
`FNM_DOTMATCH` used to have bugs (#17280) which made it error-prone but that's been fixed... Eregon (Benoit Daloze)

09:09 PM Ruby Bug #22069: Backport openssl 3.2.4/3.3.3/4.0.2

This would be great and make it much easier to install these recent Ruby versions on OS which have adopted (or soon will) OpenSSL 4.0, thank you! Eregon (Benoit Daloze)

08:48 PM Ruby Bug #22065: `make rdoc` fails with `invalid byte sequence in US-ASCII` on Ruby 4.0.4 under C locale

Should there be a test catching this kind of issue, by doing exactly the steps a user would to compile Ruby, and with LC_ALL=C? Eregon (Benoit Daloze)

07:03 PM Ruby Bug #22058: {Method,InstanceMethod}#super_method doesn't work correctly for refined method with refinements for method active in the caller's scope

I recall https://bugs.ruby-lang.org/issues/17007 (loop with `super` and refinements).
That was solved by ... Eregon (Benoit Daloze)

What do you mean by "undocumented GC behavior"?
Isn't it only ... Eregon (Benoit Daloze)

08:03 PM Ruby Bug #22021: Array#delete_if may delete wrong object if array has been altered already

The only way to iterate an Array is to use an index from 0 to size, so it's always going to be based on index.

09:08 PM Ruby Bug #22020: Inner call node without all arguments returned by RubyVM::AbstractSyntaxTree.of for call with a block

My motivation here is I would like to implement `Thread::Bactrace::Location#source_range`.
For this to work in `--parser=parse.y` mode it needs to return the same start/end line/column as Prism in all cases of `RubyVM::AbstractSyntaxTre... Eregon (Benoit Daloze)
