I do think, however, that Terry has presented some compelling use cases and I'd
like to re-iterate that based on the feedback I've received, it seems
inevitable that I'll have to implement the higher-level "typed" interface
before I can consider submitting the library for formal review.

Thank you for so succinctly re-iterating the point that Dave Handley and I have
been trying to make. I think it is important to realize that the
"encapsulation" that you get by using the typed inteface will not be
particularly good if the types just get used throughout the application rather
than being contained in the I/O part of the code. In my view, it almost
amounts to just a false sense of security.
