Instantiation

// Updates to LLVM give us better instantiation methods

NSNumber *n1 = @1000;  // [NSNumber numberWithInt:1000] 
NSNumber *n2 = @3.1415926; // [NSNumber numberWithDouble:3.1415926]
NSNumber *c = @'c'; // [NSNumber numberWithChar:'c']
NSNumber *b = @YES; // [NSNumber numberWithBool:YES]

Arrays
// before
NSArray *words = [NSArray arrayWithObjects:@"list", @"of", @"words", nil];

// after (array with some strings and numbers)
NSArray *words = @[@"list", @"of", @"words", @123, @3.14];

Dictionaries
NSDictionary *d = @{
  @"key": @"value",
  @"name": @"Joris",
  @"n": @1234,
  @3: @"string"
};
