The extension of Brian's code to rows with more than one field is obvious 
though, isn't it? 

type fbbq = 
  <foo: int->int; bar: unit->string; baz: unit->bool;quux: unit->unit>

class thing_processor = 
  object 
    method do_something (o : fbbq) =  
      (* do something that calls all those methods *)
    method do_something_else (o : fbbq) =  
      (* do something else that calls all those methods  *)
  end

-- Brian
