methods to create toys arrays and hashes
class Array
def self.toy(n=10, &block)
block_given? ? Array.new(n,&block) : Array.new(n) {|i| i+1}
end
end
class Hash
def self.toy(n=10)
Hash[Array.toy(n).zip(Array.toy(n){|c| (96+(c+1)).chr})]
end
end

Hi. I followed this from stack overflow.
Why not just extend the classes?

class Array
  def self.toy(n=10,&block)
    block_given? ? Array.new(n,&block) : Array.new(n) {|i| i+1}
  end
end   
class Hash
  def self.toy(n=10)
    Hash[Array.toy(n).zip(Array.toy(n){|c| (96+(c+1)).chr})]
  end
end

then when you need a toy hash or array to play with in irb you can just:

Hash.toy
Array.toy

Seems a little more rubyesque? No?
