Subject: [ruby-core:112509] [Ruby master Feature#19450] Is there an official way to set a class name without setting a constant?

Issue #19450 has been updated by Eregon (Benoit Daloze).


I don't think Class#inspect should ever lie, so IMO there shouldn't be a way.

In the comment above, the problem is `foo` is not assigned to a proper constant, that's the obvious fix, to assign foo to a constant.
The file in which the class is defined is another feature, maybe we should add `Module#source_location` (TruffleRuby already tracks that for interop).

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
