// Here we'll use Swift's IDE-supporting reflect()

// Per the fine engineers at WWDC, Swift's reflection support

Suppose you have a network method that only uses a single block callback

typedef void (^Handler)(BOOL success, id response, NSError *error);

- (void)makeRequestWithHandler:(Handler)handler;

But you have to make this request dozens of times, and you want to reuse the same failure handler in most cases? Easy, just have a factory function that returns a block:

typedef void (^SuccessHandler)(id response);

typedef void (^ErrorHandler)(NSError *error);

// Circular primes
// Problem 35
// The number, 197, is called a circular prime because all rotations of the digits: 197, 971, and 719, are themselves prime.
//
// There are thirteen such primes below 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97.
//
// How many circular primes are there below one million?
