To see how Hoard can help you, take a look at this code:
hoard int_array = hd(1,1,2,3,5,8,13);
NSLog(@"ints: %@", int_array.as<NSArray*>());
hoard dict = hd(@"apples",@"oranges",
@"grapefruits",@"lemons");
NSLog(@"dict: %@", dict.as<NSDictionary*>());
Basically, Hoard takes a list of things (of arbitrary type) and then holds
onto them. When you want to use them for something, specify the output type
(which could be any of the Cocoa collections, or even std::vector<id>,
std::set<id>, std::map<id,id>, etc).
