[ruby-core:112499] [Ruby master Feature#19450] Is there an official way to set a class name without setting a constant?

20 Feb 2023

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

Okay, so I tried it out, but it doesn't work consistently:

```ruby
def labeled_class(name, superclass = Object, &block)
  Class.new(superclass) do
    singleton_class.class_eval {define_method(:to_s) {name}; alias inspect to_s}
    class_eval(&block) if block
  end
end

foo = labeled_class("foo")
foo.class_eval("class Bar; end")

p foo
p foo::Bar
```

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
