[Zope-dev] ZCatalog FieldIndex design problem

[Toby Dickenson]

It is an invariant of the ZCatalog's FieldIndex that the items are
sorted. 

However python does not guarantee that the sort order of
differently-typed objects will not change. The language definition
says: 'the choice whether one object is considered smaller or larger
than another one is made arbitrarily but consistently within one
execution of a program'

http://www.python.org/doc/current/ref/comparisons.html

Are FieldIndexes relying on undefined behavior?
