Hash: new create syntax

Additional to the syntax for creating hashes we all know:

hash = { :first => "ruby", :second => "rails" }
# => {:first=>"ruby", :second=>"rails"}

hash[:first] # => "ruby"

…Ruby > 1.9.1 adds support for another syntax:

hash = { first: "ruby", second: "rails" }
# => {:first=>"ruby", :second=>"rails"}

# you still have to access a value via a symbol
hash[:second] # => "rails"
hash[second]  # NameError
