      fills in with nils
    when passed no arguments
      returns an empty vector
    from a subclass
      returns an instance of the subclass

Hamster::Vector
  #zip
    with a block
      yields arrays of one corresponding element from each input sequence
      fills in the missing values with nils
      returns nil
      can handle multiple inputs, of different classes
    without a block
      returns a vector of arrays (one corresponding element from each input sequence)
    on 10-item vectors
      behaves like Array#zip
    on 31-item vectors
      behaves like Array#zip
    on 32-item vectors
      behaves like Array#zip
    on 33-item vectors
      behaves like Array#zip
    on 1000-item vectors
      behaves like Array#zip
    on 1023-item vectors
      behaves like Array#zip
    on 1024-item vectors
      behaves like Array#zip
    on 1025-item vectors
      behaves like Array#zip
    from a subclass
