Subject: Enumerable

Am new to Ruby and have the folloiwng Question.

I have a class, say Collect, and I want to mixin Enumerable. How do I 
write the each method in Collect?

class Collect
	include Enumerable
	def initialize()
		@array = Array.new(0)
		@ct = 0
	end
	def add(item)
		@array.push(item)
		@ct += 1
	end
	def howmany
		@ct
	end
	def each
	#
	#	Not sure how to do this????
	#
	end
end
