Who wants to define the iterator protocols?

[Dan Sugalski]

Since I've obviously gone mad (or slipped into the Twilight Zone) and 
we're going to use methods for the iterators, we need to define those 
methods. In a probably futile attempt to not be a bottleneck, I'd 
like someone to step up and take a shot at defining the methods that 
have to be implemented, and the protocols they belong to, for 
iterators.

It looks like we need at least two, if not three, levels here--simple 
unidirectional iteration, bidirectional iteration, and possibly fancy 
iteration with skips and whatnot.

The important word here is *simple*. Since these are going to be our 
universal iterator methods that we're going to require everyone to 
implement, we don't want to make the levels too fancy or the methods 
too elaborate. (As you do it, ponder implementing it in either C or 
PASM. That ought to keep things under control :)
