Dealing with generators

Given any generator object g, you can perform the following operations on it:

  • g(): This scrambles the internal state of the generator and yields its next output.
  • g.min(): This tells you the smallest possible output of g() (typically 0).
  • g.max(): This tells you the largest possible output of g(). That is, the range of
    possible outputs of g() is g.min() to g.max() inclusive.
  • g.discard(n): This effectively makes n calls to g() and discards the
    results. In a good library implementation, you'll pay for scrambling the generator's internal state n times, but save any cost associated with computing the next outputs from the state.
