[ruby-core:119578] [Ruby master Bug#20808] Cannot override Data#inspect

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


> Struct and Data both assume all member readers are public:

Actually I misread. The `Struct` one uses `Struct#[]` so it would work with Struct. `Data` however has no such method, so two solutions I can think of are:

  - Use `send`, but only work for private. If instead the method is renamed or removed, it will still fail.
  - Rescue `NoMethodError`, and skip displaying that field.

Bug #20808: Cannot override Data#inspect
https://bugs.ruby-lang.org/issues/20808#change-110197

* 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
