Subject: [ruby-core:86123] [Ruby trunk Feature#14579] Hash value omission

Issue #14579 has been updated by matz (Yukihiro Matsumoto).


I prefer this syntax to #11105, but this introduces a Ruby-specific syntax different from ES6 syntax.
Besides that, I don't like both anyway because they are not intuitive (for me).

Feature #14579: Hash value omission

----------------------------------------
How about to allow value omission in Hash literals:

```ruby
x = 1
y = 2
h = {x:, y:}
p h #=> {:x=>1, :y=>2}
```

And in keyword arguments:

```ruby
def login(username: ENV["USER"], password:)
  p(username:, password:)
end

login(password: "xxx") #=> {:username=>"shugo", :password=>"xxx"}
```
