This is just one manifestation of what I consider a
serious shortcoming of the pickle format for long-term
storage: it ties the data to implementation details
of the program.

When I brought this up earlier, various people assured
me that it wasn't a problem in practice. I think we're
seeing one situation here where it *is* a problem.
