----------------------------------------
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"}
```
