Dumb Ruby password generator

passwordy.rb

# Returns an enumerator that generates password from the standard dictionary
# Only parameter is the number of words to use.
# Example: passwordy(2).next -> "GarlicUngulp"

def passwordy(wc=4)
	words = File.readlines('/usr/share/dict/words')
		.select {|w| w.size>5 && w.size<=9}
		.shuffle
  Enumerator.new do |yielder|
    yielder.yield(words
      .take(wc)
      .map {|w| w.chomp.capitalize}
      .join)
    words = words.drop(wc)
  end
end
