05:27 PM Ruby Misc #21299 (Closed): Proposal: Remove `continuation` gem

Continuations have been obsolete since Ruby 2.2 but still add complexity to the core codebase. I propose removing all continuation support from Ruby Core.
### Reasons
#### Simplifies fiber code
- Current fiber code in `cont.c`... ianks (Ian Ker-Seymer)

02:19 AM Ruby Feature #19057: Hide implementation of `rb_io_t`.

> With one tweak: not int rb_ioptr_descriptor(struct rb_io *ioptr); but int rb_io_descriptor(VALUE io);.

I have mixed feelings about this. On one hand, it does successfully hide the implementation. On the other, casting pointers t... ianks (Ian Ker-Seymer)

05:31 AM Ruby Feature #19236: Allow to create hashes with a specific capacity from Ruby

I worry that new Rubyists might be confused with the `Hash.new(capacity: n)` semantics.
For example, `Hash[capacity: 5]` can look very similar to `Hash.new(capacity: 5)`. It wouldn’t be unreasonable to assume they are the same thing… ... ianks (Ian Ker-Seymer)

03:01 AM Ruby Feature #19627: Ensure the VM is alive before accessing objspace in C API

For documentations sake, [he's a real world reproduction of this issue that happens when calling TLS destructors](https://github.com/bytecodealliance/wasmtime-rb/actions/runs/4850597226/jobs/8643651566?pr=181). In Ruby < 3.3-dev, I'm abl... ianks (Ian Ker-Seymer)

02:23 AM Ruby Feature #19627: Ensure the VM is alive before accessing objspace in C API

That’s a good idea. I’ll put a patch up for that.
So far I’ve encountered this issue this issue in `rb_gc_adjust_memory_usage` and `rb_during_gc`, so I still think having the ability to check for a Ruby VM is important for writing ro... ianks (Ian Ker-Seymer)

11:29 PM Ruby Feature #19627 (Closed): Ensure the VM is alive before accessing objspace in C API

Currently, there is no supported way to check if the Ruby VM has been shut down. There are a couple of workarounds that I know of:
1. Setup an exit handler which sets a global variable (like I did in https://github.com/tmm1/stackprof/... ianks (Ian Ker-Seymer)

06:03 AM Ruby Feature #19315: Lazy substrings in CRuby

> It seems a good idea to introduce a variant of `RSTRING_PTR` which doesn't guarantee \0-termination, so such callers can then use the existing bytes always without copy.
It would be nice to have a way to get the raw parts of a strin... ianks (Ian Ker-Seymer)
