This is stopping from using dynamically defined methods from ractors. E.g. in Ruby [libtorch](https://github.com/orlando-labs/torch.rb/blob/2c8c1c89ded3ac924a19020d6c747582d1c828cc/lib/torch.rb#L256). So after calling rb_ext_ractor_safe in extension, I am trying to do something like:
```ruby
cls.define_singleton_method('new', Ractor.make_shareable(Proc.new { ... })
```
That leads to every second closure assignment to false.

Hi. I encountered strange behaviour or shareable procs when every even closured shareable variable becomes the FalseClass instance.
``` ruby
[usr@srvr ~]$ irb
3.0.1 :001 > v1, v2, v3, v4 = :a, :b, :c, :d
=> [:a, :b, :c, :d]
3.0.1 :002 > p = Proc.new { p v1, v2, v3, v4 }
=> #<Proc:0x000000000248ed18 (irb):2>
3.0.1 :003 > p.()
:a
:b
:c
:d
=> [:a, :b, :c, :d]
3.0.1 :004 > Ractor.make_shareable(p).()
:a
false
:c
false
=> [:a, false, :c, false]
```

Hi. I encountered strange behaviour or shareable procs when every even closured shareable variable becomes the FalseClass instance.
``` ruby
[usr@srvr ~]$ irb
3.0.1 :001 > v1, v2, v3, v4 = :a, :b, :c, :d
=> [:a, :b, :c, :d]
3.0.1 :002 > p = Proc.new { p v1, v2, v3, v4 }
=> #<Proc:0x000000000248ed18 (irb):2>
3.0.1 :003 > p.()
:a
:b
:c
:d
=> [:a, :b, :c, :d]
3.0.1 :004 > Ractor.make_shareable(p).()
:a
false
:c
false
=> [:a, false, :c, false]
```
