Getting the next line with the iterator

I find this the most readable way to do it, though using generator is
probably slower than just keeping track of the last 3 lines as you go
forward:

require 'generator'
list =
File.open('toto.txt', 'rb') do |myFile|
  g = Generator.new(myFile)
  while g.next?
    if g.next =~ /regExp/
      3.times { list << g.next }
    end
  end
end
puts list
