ruby-core #122715
Issue #21454 has been updated by nobu (Nobuyoshi Nakada).
Use no-dbg.rb with `RUBYOPT=-rno-dbg` when you run without `rdbg`.
```ruby
class Binding
def break = nil
end
```

Feature #21454: "undefined method 'break' for an instance of Binding"
https://bugs.ruby-lang.org/issues/21454#change-113992
* Author: vo.x (Vit Ondruch)
* Status: Open
----------------------------------------
Running my code with `rdbg` and using `binding.break`, it is a bit unfortunate that subsequently running the code without `rdbg`, it fails with error such as:
~~~
NoMethodError:
undefined method 'break' for an instance of Binding
~~~
Could this method become no-op if the `rdbg` is not loaded? If there was some concern about this, then it could print some helpful warning or what not.
