A Query is a predicate applied to a Set/Collection of items. In the
new world, you will be able to apply predicates to any collection of
item. At the moment this happens via a FilteredCollection kind
which accepts the predicate as an argument. Right now my intention
is to support the predicate language from the existing Query
implemenatation. I have a feeling the Phillip may be interested in
something more Pythonic, which may also be a possiblity. Concretely:
c = UserCollection(.....)
fc = FilteredCollection(c, "i.startDate < '3/3/2005 03:15'")
An interesting approach to a python-ic query language is to use actual
Python objects and operator overloading... it's interesting to see how
SQLBuilder does it: http://sqlobject.org/docs/SQLBuilder.html
problem is, python doesn't seem to have the complete flexibility needed
(unlike say Lisp)
