[ruby-core:119576] [Ruby master Bug#20808] Cannot override Data#inspect

["byroot (Jean Boussier) via ruby-core" <ruby-core@ml.ruby-lang.org>]

Issue #20808 has been updated by byroot (Jean Boussier).


So the problem isn't with `inspect`, as it only reproduce in `irb`.

It's coming from `pretty_inspect`:

```
>> d.pretty_inspect
/opt/rubies/3.3.5/lib/ruby/3.3.0/pp.rb:432:in `public_send': private method `name' called for an instance of Dog (NoMethodError)

          q.pp public_send(member)
               ^^^^^^^^^^^

----------------------------------------
Bug #20808: Cannot override Data#inspect
https://bugs.ruby-lang.org/issues/20808#change-110195

* Author: maicolben (Maicol Bentancor)
* Status: Open
* ruby -v: 3.3.5
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
Given the next code:
```
Dog = Data.define(:name) do
  def inspect
    "Hello!"
  end

  private
  attr_reader :name
end

Dog.new(name: "Fido")
```

It throws an error:
- An error occurred when inspecting the object: #<NoMethodError: private method `name' called for an instance of Dog> 

And isn't using my `inspect` function
