Hello!
Nobody noted the message in c.l.py, let me try to ask you before I file

I replaced cPikle.dump with pikle.dump and got infinite rcursion. The
traceback is below.
What's that? Are there any limits that an object to be pikled must
follow? Could it be a tree with loops? (I am pretty sure it could - I used
the program for years, and data structures was not changed much). Could it
be "new" Python class? (Recently I changed one of my classes to be derived
from builtin list instead of UserList).
Well (or not so well), the traceback:
