Issue #15574 has been updated by ko1 (Koichi Sasada).

Status changed from Open to Rejected

it seems difficult to apply this proposal because of compatibility (and productivity). rejected.

----------------------------------------
Feature #15574: Prohibit to pass a block on super() implicitly
https://bugs.ruby-lang.org/issues/15574#change-82201

* Author: ko1 (Koichi Sasada)
* Status: Rejected
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
* Target version: 
----------------------------------------
As described in [Feature #15554], `super()` (not `super`) pass the given block.

```
class C
  def foo
    p block_given?
  end
end

class C1 < C
  def foo
    super   #=> true
    super() #=> true
  end
end

C1.new.foo{}
```

`super` (without parameters) passes all passed parameters so it is no surprise to pass given block. 

However, `super()` (with parameters. In this case, it passes 0 parameters) also pass given block implicitly.

I'm not sure who use this behavior, but I think it is simple to prohibit such implicit block passing.
