Subject: [ruby-core:113903]  [Ruby master Bug#19731] Can’t call an instance method inside an Endless method definition

Issue #19731 has been reported by ttanimichi (Tsukuru Tanimichi).



----------------------------------------

Bug #19731: Can���t call an instance method inside an Endless method definition

https://bugs.ruby-lang.org/issues/19731



* Author: ttanimichi (Tsukuru Tanimichi)

* Status: Open

* Priority: Normal

* ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22]

* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

----------------------------------------

Can���t call an instance method inside an Endless method definition.



```

$ ruby -v

ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22]



$ cat withend.rb

class A

  def show

    puts 'ok' if params

  end



  def params

    42

  end

end



A.new.show



$ ruby withend.rb

ok



$ cat endless.rb

class A

  def show = puts 'ok' if params



  def params

    42

  end

end



A.new.show



$ ruby endless.rb

endless.rb:2:in `<class:A>': undefined local variable or method `params' for A:Class (NameError)



  def show = puts 'ok' if params

                          ^^^^^^

	from endless.rb:1:in `<main>'

exit status: 1

```



But, the example below works fine. Is this an expected behavior?



```

$ cat endless2.rb

class A

  def show = puts params



  def params

    42

  end

end



A.new.show



$ ruby endless2.rb

42

```
