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)

09:02 PM Ruby Bug #22020: Inner call node without all arguments returned by RubyVM::AbstractSyntaxTree.of for call with a block

```

08:19 PM Ruby Bug #22021 (Rejected): Array#delete_if may delete wrong object if array has been altered already

IMO it's not reasonable for `Array#delete_if` to do anything else than what it already does.
How can `Array#delete_if` know which element you deleted and whether it should delete or not?
The block returns true for the second 2nd block ca... Eregon (Benoit Daloze)

11:40 AM Ruby Feature #21953: Allow accessing unshareable objects within a Ractor-local Ruby Box

@tikkss I think there is an issue with your accounting of memory because it doesn't match the RSS of the worker process.
This is running your example as-is.
