----------------------------------------
Bug #13370: instance_exec occurs "no receiver given (ArgumentError)"
https://bugs.ruby-lang.org/issues/13370#change-63864

* Author: ta1kt0me (hiroki tokutomi)
* Status: Rejected
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.4.1
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
ArgumentError occurs in 2.4.1 on below code. It's the same in trunk.

```ruby
class Foo
  def one
    puts 1
  end
end

Foo.new.instance_exec(&:one)
# => ArgumentError: no receiver given
```

But it's differece behavior with 2.4.0 . Is this expected ?

```
# 2.4.0
Foo.new.instance_exec(&:one)
# 1
# => nil
```
