[ruby-core:112774] [Ruby master Feature#19450] Is there an official way to set a class name without setting a constant?

9 Mar 2023

      Issue #19450 has been updated by ioquatix (Samuel Williams).

Status changed from Open to Closed

Thanks for all the discussion, here are the proposals:

- https://bugs.ruby-lang.org/issues/19520 (parameter to new)
- https://bugs.ruby-lang.org/issues/19521 (Module#name=)

They are alternatives and also complementary, i.e. we could do both.

This is the best I could come up with:

```ruby
klass = Class.new

Object.const_set("Klass", klass)
Object.send(:remove_const, "Klass")

puts klass.new
# => #<Klass:0x0000000100a9d688>
```

Can we do better?

What about something like:

```ruby
Class.new(name: "Klass")
```

or

```ruby
Class.new do
  def self.name
    "Klass"
  end
end
```

etc
