Subject: Hash#inject argument syntax

The code below works but I do not understand the  "(key, value)"
parenthesis syntax.  I have not seen it before.  Could someone
explain?

class Hash
def symbolize_keys
   inject({}) do |options, (key, value)|
    options[key.to_sym] = value
    options
  end
end
end
