> Why a new parameter?
because I misread the ticket, I didn't notice the `o`.
I do think `^` for offset is pure genius though. byroot (Jean Boussier)

08:10 AM Ruby Feature #21796: unpack variant that returns the final offset

It would be useful indeed, but I'm not sure a new method is the best way?
I think the simplest would be a new keyword parameter:
```ruby
offset, *values = bytes.unpack("Ro", offset: offset, return_offset:true)
```

08:15 AM Ruby Feature #21791: Implement Set#compact/Set#compact!, these should return Set instead of Array

Since `Set#delete` is O(1) performance and return self, why not just:
```ruby
>> Set[1, 2, nil, 3].delete(nil)
=> Set[1, 2, 3]

07:57 PM Ruby Revision 57c4cd9a (git): thread_sync.c: eliminate GET_EC() from queue_do_pop

If the queue was allocated without calling initialize,

07:38 AM Ruby Feature #21788 (Open): Promote Thread::Monitor to a core class

I propose to promote `Thread::Monitor` as a core class convenience.
### The rest of `monitor.rb`
The `monitor` stdlib als... byroot (Jean Boussier)
