Subject: [ruby-core:94880] [Ruby master Bug#16106] UnboundMethod owner	points to base class

Issue #16106 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Closed

The documentation for `owner` states: `Returns the class or module that defines the method.`.  The example given in the documentation shows `method` being called on a Range instance, but having an owner of Enumerable.  So I don't think documentation updates are necessary, and this can be closed.

Bug #16106: UnboundMethod owner points to base class
https://bugs.ruby-lang.org/issues/16106#change-81496

* Author: sbellware (Scott Bellware)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin17]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
This may not be a bug. It may be my misinterpretation of the feature.

When using UnboundMethod#owner on a class that was created with `Class.new(SomeBaseClass)`, the owner is reported as the `SomeBaseClass `rather than the new class.

This was a surprising outcome, since I presumed that the owner method would point to the class rather than the class's base class.

Example:

```
class SomeClass
  def some_method
  end
end

C = Class.new(SomeClass)

m = C.instance_method(:some_method)

pp m.owner
# => SomeClass

# I would have expected the owner to be C
```

Is this expected behavior?

Thanks,
Scott
