Sorry folks the example was not correct

irb(main):001:0> drill_down = lambda do |obj, method_names|
irb(main):002:1*        o ||= obj
irb(main):003:1>        method_names.split('.').each {|m| o = o.send(m)}
irb(main):004:1>        o
irb(main):005:1> end
=> #<Proc:0x40221e48@(irb):1>
irb(main):006:0> drill_down.call(1,'succ.to_s')
=> "2"
irb(main):007:0> drill_down.call(1,'succ.succ.succ.to_s')
=> "4"
irb(main):008:0>

This is what I currently have working.  I'm using it to define the columns
in a report so I need to determine the result of arbitrary fields within
the object model.  I just look at the code and think there is a better way.
