My nitpick with continuations is that it does not fit the model of
object programming.

Continuations saves the function context to be able to continue the
function at a later time.  The information is tied to the function
activation record.

The object programming style on the other hand suggest that important
data structures should be tied to the object, not the function.

The need for continuations should be lessened if one has some light weight
process implementations at hand.

Actually I am still wondering about how one is supposed to build a
general pupose iterator in a OO language.  One can always have
Ad Hoc iterators, but a consistent iterator interface I suspect would
be hard to do.
