[ruby-core:122523] [Ruby Bug#21440] Cannot create instances of frozen Data subclasses

[jeremyevans0 (Jeremy Evans) via ruby-core]

Issue #21440 has been reported by jeremyevans0 (Jeremy Evans).

----------------------------------------
Bug #21440: Cannot create instances of frozen Data subclasses
https://bugs.ruby-lang.org/issues/21440

* Author: jeremyevans0 (Jeremy Evans)
* Status: Open
* Backport: 3.2: REQUIRED, 3.3: REQUIRED, 3.4: REQUIRED
----------------------------------------
This fails since Data was added in Ruby 3.2:

```ruby
Class.new(Data.define(:a)).freeze.new
# can't modify frozen #<Class:#<Class:0x000079cf41253160>>: #<Class:0x000079cf41253160> (FrozenError)
```

Note that the error occurs even before the ArgumentError due to the missing argument to `new`.

This doesn't happen on classes created with `Data.define` (only subclasses of those classes):

```ruby
Data.define(:a).freeze.new
# missing keyword: :a (ArgumentError)
```
