How do you determine whether a block contains a heredoc? Consider:
- `{ <<X }`: heredoc
- `{ x<<X }`: shift operator

02:39 PM Ruby Feature #21998: Add {Method,UnboundMethod,Proc}#source_range

@matz What should the following return?
```ruby
f = proc { <<END }
xxx
END
f.source_range #=> Start position: from the `p` of `proc`? Or from the `{`?
#=> End position: up to the `}`? Or up to the `D` of `END`?

05:48 AM Ruby Feature #21795: Methods for retrieving ASTs

As matz pointed out in #note-11, the ABI versioning approach would leave master in a routinely broken state. As a maintainer of error_highlight, I cannot accept this. Not being able to verify error_highlight's behavior against code using... mame (Yusuke Endoh)

06:18 AM Ruby Bug #21969 (Third Party's Issue): fork() + Socket.getaddrinfo() triggers SIGSEGV/SIGABRT via libsystem_trace.dylib on macOS 26 (darwin25) x86_64 and ARM64

#21790 also identifies `_os_log_preferences_refresh` in `libsystem_trace.dylib` as the crash site (see note #4). The NAT64 code path (`_gai_nat64_second_pass`) appears higher in the call stack, but the actual fault is the same stale shar... mame (Yusuke Endoh)

12:10 AM Ruby Feature #21960: Improve #backtrace to not confuse terminals

Has the reporter confirmed that this change would actually make backtraces clickable in Ghostty? I suspect it would not.
I found the relevant Ghostty discussion (I'm surprised it wasn't linked in the description):

02:44 AM Ruby Feature #21932: `MatchData#get_int`

Here is a supplement to Matz's decision.
This method will basically follow the behavior of `String#to_i`.
The base can be specified as the second argument:

"2024" =~ /(\d+)/
