ri--Ruby Interactive reference

ri displays descriptions of Ruby's built-in methods, classes, and
modules.  Run "ri each_with_index" and you get:

	--------------------------------------------------------
	  enumObj.each_with_index {| obj, i | block }  -> nil
	--------------------------------------------------------

	  Calls block with two arguments, the item and its index,
	  for each item in enumObj.

	     hash = Hash.new
	     %w(cat dog wombat).each_with_index {|item, index|
	       hash[item] = index
	     }
	     hash   #=> {"dog"=>1, "wombat"=>2, "cat"=>0}
