Tinkering with a predicate builder in Objective-C.
/* I'm trying to come up with with a general predicate builder in Objective-C, that can build NSPredicates for
arbitrary classes. I want to write something like this:
predicate = [[[[[builder name] contains:@"ilja"] age] greaterThan:@20] predicate];
But the compiler insists on sprinkling ids everywhere.
predicate = [[(id)[[(id) [(id) builder name] contains:@"ilja"] age] greaterThan:@20] predicate];
Any ideas how to omit the 'id' casts? Also, need a good idea for or and not methods.

This code crashes unless CFBridgingRetain is called. Any Ideas why?
