Details:

I am afraid there is a bug in the NSPredicate class.
The expected result of exec below is output of "1", but actual result is
"0".
--
 NSString* fmt = @"SELF == 'aaa'";
 NSPredicate* predicate    = [NSPredicate predicateWithFormat:fmt] ;
 BOOL ok = [predicate evaluateWithObject:@"aaa"];
 NSLog(@"[predicate evaluateWithObject:@\"aaa\"] -> %d", ok);
--

I think the problem is in :
 File: NSPredicate.m
 Implementation GSEvaluatedObjectExpression
 Method -(id)expressionValueWithObject:(id)obj context:(NSDictionary*)info  



Index: NSPredicate.m
