OK, so how else do I do it? The problem is that I am trying to create a
class whose instances will be ephemeral, lasting only for one
transaction, but which can call objects within the ZODB. Essentially my
classes are glorified Pluggable Brains, but they have to combine data
from several database queries, which are of course all Z SQL methods.
The data cannot be passed as class initialisation parameters as the
class needs to decide what calls to make depending on the data from
other queries.
