Iterates the given block over all prime numbers. Note that enumeration starts from the current position of internal pointer, not rewound.

# File lib/prime.rb, line 480
def each
  return @generator.dup unless block_given?
  loop do
    yield succ
  end
end

Returns the next prime number and forwards internal pointer.

  @generator.succ
end
