I have considered making something like this, except with more
pleasant expressions. Maybe something like:
query = AND(VAR.callLogTable.State == "NJ", VAR.extension == 1111,
VAR.duration > 60)
With later Python versions (2.0, 2.1?) you can overload ==, <, >,
etc. fairly well. You cannot meaningfully overload and, or, or not
(though you could overload &, |, and ~). You also will probably get
bad results if you did "NJ" == VAR.callLogTable.State, since "NJ" gets
the first chance to test equality, and it'll just return False instead
of a fancy where-clause object.
I don't know if this would work with DDOS anyway, but it could work
well for programmers.
