Hi Scott,
Pickling is serializing arbitrary object-oriented data structures. That is,
converting them into a byte stream for storage, transmission over a network or
iterative navigation as in this case. It is a more complex process than you
might imagine. If you want more information, search the web for information on
Python's pickle module.

Sometimes I really love the developers at Oracle...... This should be good
fodder for Eric P.
Does anyone have experience with infamous pickler Fetch which shows up in
this explain plan the select is on index organized nested tables (Nested
objects)? It's obvious that someone in internals has a good sense of humor.
I guess this is the way Oracle dereferences the embedded collections?
