Complete the Code
What could potentially go wrong with this particular error handling code?
```objc
// What could potentially go wrong with the code below?
NSError *theError;
BOOL result = [anObject doSomethingThatCanFailWithError:&theError];
if (theError) {
NSLog(@"The operation failed! %@", theError);
}
```

Compiler Error
This week's Compiler Error has a theme: Blast from the past!
1 - Swift Literals: Although Dictionaries prohibit it, ExpressibleByDictionaryLiteral allows for multiple entries with the same key.
2 - Emacs key bindings in Cocoa: You may know of the ⌘⌫ command to delete the entire line to the left of the text cursor, but ⌃K can be used to delete the line to the right of the text cursor.
3 - Objective-C method names in the iOS SDK: convolveWithDestination:tempBuffer:sourceOffsetToRegionOfInterestX:sourceOffsetToRegionOfInterestY:kernel:kernelHeight:kernelWidth:divisor:backgroundColor:options: is one of many related Objective-C methods in the Accelerate framework for manipulating images.
4 - Unicode names for Mac modifier keys: Located between the control and command keys on the keyboard, the option key is unoriginally called OPTION KEY in the unicode specification, but was also known as the “closed apple key” on Apple II series computers.
