The downsides are:
1. If the library requires that you use the actual address stored in string
variable kSomeCStringConstant then it may fail because @(kSomeCStringConstant)
may create a second object at a different address.
2. The compiler is not currently smart enough to optimize
@(kSomeCStringConstant) into a constant string object, so it may allocate a new
autoreleased string object every time it runs that line.
