81	contracts -- basic iterator	Fred T. Hamster	bugdock	"iterator<class contents>

  define virtual next()

  define a sentinel that means stop?


like so?
contents *next();

sentinel just being nil on nothing left?

how to iterate on null in list then?
don't, i guess.

--->  adapt this concept in the list class and see if it righteously simplifies everything.
