I no longer think this way about programs I write.  Enumerable and  
block argument multiple assignment allow you to not care about what  
type of object is on the left hand side.  Instead you can use friendly  
variable names to make your code very readable.

An arbitrary example would be:

meetings = {
   'eric' => ['thursday at 1100', '206-555-0000']
   'ryan' => ['thursday at 1300', '206-555-0001']
}

meetings.each do |callee, (time, phone_number)|
   puts "call #{callee} at #{time} on #{phone_number}"
end
