Ok, so this:

%w[uri net/http].each{|l|require l}
10.times do
  Thread.new
{Net::HTTP.get_response(URI.parse('http://www.google.com/'))}
end

is equal to this:

require 'net/http'
require 'uri'
10.times do
  Thread.new
{Net::HTTP.get_response(URI.parse('http://www.google.com/'))}
end

Good, I've never used require with array.

But if I run the code above I get an error: url_call.rb:4: odd number 
list for Hash

I think it's because of the curly braces that are viewed like an hash, 
right? I don't know how Thread works in Ruby, but it seems that the 
statements in the curly braces need to be on the same line as Thread.new 
otherwise it give the error above...
