Issue #16253 has been updated by ioquatix (Samuel Williams).


Here are some real world examples from my code:

```
def self.for(*arguments, &block)
	self.new(block, *arguments)
end

# Nicer?

def self.for(..., &block)
	self.new(block, ...)
end
```

Module to be prepended:

```
module Connection
	def initialize(*)
		super
		
		# Other stuff
	end
end

# Nicer?

module Connection
	def initialize(...)
		super(...)
		
		# Other stuff
	end
end
```

Many repeated code:

```
def self.one(*arguments, **options)
	append One.new(*arguments, **options)
end

def self.many(*arguments, **options)
	append Many.new(*arguments, **options)
end

def self.split(*arguments, **options)
	append Split.new(*arguments, **options)
end

# Nicer and more maintainble?

def self.split(...)
	append Split.new(...)
end
```

There are many more but since this feature is exciting to me, I wanted to give some specific use cases so we can evaluate how they would benefit/change.

Feature #16253: Shorthand "forward everything" syntax
https://bugs.ruby-lang.org/issues/16253#change-82180

* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
What about using this:

```ruby
  def foo(*)
    @bar.foo(*)
```

to mean this:

```ruby
  def foo(*a, **o, &b)
    @bar.foo(*a, **o, &b)
```

I used `def foo(*)` because that's currently valid ruby code, but I'm fine with any syntax.

It's like the no-parentheses `super` shorthand, but for any method.

It makes it easier to write correct forwarding code. 

If rubyists must be told they have to change their forwarding code in 2.7 (due to keyword arguments), the pill might be easier to swallow if the change is a reduction rather than an increase in verbosity.

And we'd even be future-proof if an eventual FOURTH kind of parameter is introduced!!!!
