[ruby-core:112604] [Ruby master Feature#19450] Is there an official way to set a class name without setting a constant?

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


I wondered about whether your point of class name consistent was valid, but I found cases like this:

```
irb(main):005:0> k = Class.new
=> #<Class:0x000000010488b9b8>
irb(main):006:0> K = k
=> K
irb(main):007:0> k.name
=> "K"
irb(main):008:0> Object.send(:remove_const, :K)
=> K
irb(main):009:0> k.name
=> "K"
irb(main):010:0> j = Class.new
=> #<Class:0x000000010488c318>
irb(main):011:0> K = j
=> K
irb(main):012:0> K.name
=> "K"
irb(main):013:0> k.name
=> "K"
irb(main):014:0> j.name
=> "K"
```

So, it's not possible that the class path is actually logical... and the same applies to nested classes.

```
irb(main):015:1* class k::J
irb(main):016:0> end
=> nil
irb(main):017:0> k::J
=> K::J
irb(main):018:0> k.name
=> "K"
irb(main):019:0> k == K
=> false
irb(main):020:0> K::J
(irb):20:in `<main>': uninitialized constant K::J (NameError)
    from <internal:kernel>:187:in `loop'                  
    from -e:1:in `<main>'  
```

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
