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 +).

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?
