Flowdock
each() public

Calls block once for each key in hsh, passing the key and value to the block as a two-element array. Because of the assignment semantics of block parameters, these elements will be split out if the block has two formal parameters. Also see Hash.each_pair, which will be marginally more efficient for blocks with two parameters.

   h = { "a" => 100, "b" => 200 }
   h.each {|key, value| puts "#{key} is #{value}" }

produces:

   a is 100
   b is 200
