# In Rails 3 The require for the Numeric time helpers is simply:
# require 'active_support/core_ext/numeric/time'
# In Rails 2, it's all of this:

require 'active_support/core_ext/numeric/time'
require 'active_support/duration'
require 'i18n'
  
class Numeric #:nodoc:
  include ActiveSupport::CoreExtensions::Numeric::Time
end

require 'active_support/core_ext/array/conversions'

class Array #:nodoc:
  include ActiveSupport::CoreExtensions::Array::Conversions
end


# This is just a little taste of how many more things you're "not doing" in Rails 3.

# tl;dr Rails 2 sucks, Rails 3 will make the suck go away.
