Feature #9778: Bring shortcut methods to Hash

My obsession with easy syntax annoys me when I see `Hash#merge` does not have a shortcut in the form of a mathematical operation (like `-` or `+`).

~~~ruby
h_one = { :foo => "bar", :this => "that", :all => "nothing" }
h_two = { :foo => "this", :ruby => "awesome" }

# this isn't as pretty
h_one.merge(h_two)
  =>  { :foo => "this", :this => "that", :all => "nothing", :ruby => "awesome" }

# as this
h_one+h_two
  => { :foo => "this", :this => "that", :all => "nothing", :ruby => "awesome" }`
~~~

Why doesn't this exist in Ruby?
