[ruby-core:113033] [Ruby master Feature#19555] Allow passing default options to `Data.define`

28 Mar 2023

      Issue #19555 has been reported by p8 (Petrik de Heus).

----------------------------------------
Feature #19555: Allow passing default options to `Data.define`
https://bugs.ruby-lang.org/issues/19555

* Author: p8 (Petrik de Heus)
* Status: Open
* Priority: Normal
----------------------------------------
Defining a subclass of `Data` with default attributes can currently be implemented by overriding `intialize`:
```ruby
class Point < Data.define(:x, :y, :z)
  def initialize(x:, y:, z: 0) = super
end

p Point.new(1, 2)
#=> #<data Point x=1, y=2, z=0>
```

It would be nice if we could do it in `define` as well:

```ruby
Point = Data.define(:x, :y, z: 0)
```
