iterators instead of callbacks.

[Antoon Pardon]

My current understanding is that callbacks are used in a number
of places because they predate iterator. But now that we have
iterators these would be better suited. I'm thinking about the
FTP-lib now where iterator equivallents of retrbinary and retrlines
methods may be more easily usable then the current versions with a
callback.

So I was wondering, are such transformations in the pipeline
somewhere?
