Why isn\'t it possible to have this: def main(args:Array[String]) { val whatever:String // Have it uninitialized here
Suppose I have this simple class: public class Pair { public readonly object first; public readonly object second;
Why are ints and doubles immutable? What is the purpose of returning a new object eac开发者_高级运维h time you want to change the value?

I\'m wondering how to implement immutable data structures in C++ (or C). I\'m searching for a book or paper (or a relatively simple and documented implementation) on the subject and I haven\'t managed
Nostalgic for Collections.unmodifiableMap(), I\'ve been implementing a read-only IDictionary wrapper based on this discussion, and my unit test quickly ran into a problem:
I want to have immutable types that can, ideally, sort out their own hashing and equality, but can be easily subclassed. I started off using namedtuple:
I have no idea what immutable class should look like but am pretty sure this one is. Am I right? If I\'m not please specify what should be added/removed.
Update: It occurred to me after posting this question that the main downside of this idea would simply be that such a type would be easy to use improperly. That is, the type would have to be used in a
