Hash Shorthand

Description

The ES6 update to Javascript added object shorthand. I propose that a similar hash shorthand be added to Ruby.

Before

name = 'Matz'
country = 'Japan'

attributes = {
  name: name,
  country: country
}

After

name = 'Matz'
country = 'Japan'

attributes = {
  name,
  country
}

This would be very useful when building hashes from keyword arguments (especially with default values):

def build(name: 'John Doe', age: 100, country: 'Earth', )
  attributes = {
    name,
    age,
    country
  }
end
