Issue #9755 has been reported by Shugo Maeda.

----------------------------------------
Feature #9755: Thread::Backtrace::Location#defined_class
https://bugs.ruby-lang.org/issues/9755

----------------------------------------
I'd like Thread::Backtrace::Location#defined_class.

```ruby
class X
  def foo
    p caller_locations.first.defined_class #=> Y
  end
end

class Y
  def bar
    X.new.foo
  end
end

Y.new.bar
```

nobu created a patch:

  https://github.com/nobu/ruby/compare/backtrace-self%2Bclass

But this patch has two problems:

1. The patch adds Thread::Backtrace::Location#self, but it's weird that a location has self.
2. Thread::Backtrace::Location#class conflicts with Kernel#class.
   So I proposed defined_class as the method name.
