Other Languages

Anyone know of other languages that support this? Wouter Lievens 10:47, 28 Apr 2005 (UTC)

Strange, I never noticed before you asked: c++ is the only major language I can confirm uses const variables... Maybe it's because it sounds like such an oxymoron. Java seems to have a const keyword, but doesn't use it. Java's final keyword is similar when used with a member variable however. I believe that const may be valid C now since C99, but it'd be better to double-check that. I know of no other language with anything anologous to mutable. Const correctness seems to be a wholly C++ phenomenon. TheIncredibleEdibleOompaLoompa 17:19, 2005 Apr 28 (UTC)
C# also has a const keyword (and a readonly keyword), though it really has nothing like const correctness in C++. IIRC, it makes a reference immutable, not the object itself. OracleofTroy
Yeah Java has final and C# has const but it's not the same. What really matters (in this article) is the const correctness of methods. Wouter Lievens 07:48, 12 May 2005 (UTC)[reply]

Immutabitity

I barely know the semantic of const, so I may be wrong but isn't this article talking about the same thing as immutable object? Of course, there is a difference but I don't think it is much to warrant two separate articles. So I am adding merge tag. Feel free to correct me. -- Taku 09:54, Jun 23, 2005 (UTC)
