Accessing multiple attributes/methods of an object with a concise syntax.

object_attrlist.rb

module Attrlist
  def /(attrlist)
    attrlist.map { |a| send(a) }
  end
end

class Time
  include Attrlist
end

# Use an attribute list to access multiple attributes of an object
# at once, receiving the values back as an array.
#
# == Example Usage
#
# >> t = Time.new
# => 2014-03-23 11:44:05 -0500  
#
# >> t/[:year, :month, :day]
# => [2014, 3, 23]  

So, for instance, if you wanted to create a new Time object with only a couple new specific attributes:

>> specific_time = Time.new(*t/[:year, :month, :day], hour, minute)
=> 2014-03-23 09:34:00 -0500
