----------------------------------------
Bug #11212: defined?(foo()) ignores respond_to_missing?
https://bugs.ruby-lang.org/issues/11212#change-79899

* Author: ko1 (Koichi Sasada)
* Status: Closed
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
* Target version: 
* ruby -v: 2.3dev
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
```ruby
class C
  def respond_to_missing? *args
    true
  end

  def test
    p defined?(non_exist_method())
  end
end

C.new.test
```

This script prints only `nil`. It ignores `respond_to_missing?`.
It should be a bug.
