Subject: Re: Enumerable#zip with File IO

Hi,

this simply makes no sense. When you go through each line "by hand", the 
"zip" is completely useless. You might as well write

file = open( ARGV[0], "r" )
puts "#{1}: #{file.readline}"
puts "#{2}: #{file.readline}"
...

I guess what you actually want is something like this:

File.foreach(ARGV[0]).with_index do |line, i|
  puts "#{i + 1}: #{line}"
end
