draft of a dictionary comprehension idea for obj-c: generating dictionaries over collections using simple-ish block syntax.
- (NSDictionary *)dictionaryOfPeople:(NSArray *)people {
return [people dictionaryViaEnumeration:^(Person *person, id *key, id *value) {
*key = person.identifier;
*value = person.name;
}];
}
