Semantic of the const keyword

[gallandarakhneorg]

Is the semantic of the keyword "const" coming from the "const" in C++, "const" or "immutable" in D, "const" or "readonly" in C#, or "final" in Java?

The code from the "counting" demo indicates that the semantic of "const" is the same as the semantic of "final" in Java:

const AtomicInteger count = new AtomicInteger
...
count.incrementAndGet 

It may be confusing for developers because "const" means "read only" for most of them.

Moreover, it seems correct to write with the current semantic:

const BigInteger abc = new BigInteger(4)
abc.add(6)

I think it is in contradiction with the use of "const" in the other programming languages. The following "equivalent" code is not working with these languages:

const int abc = 4;
abc = abc + 4;

I agree that "const" may not be best choice.
Just to notice, the code

const int abc = 4;
abc = abc +4;

Will also fail on SARL, since you can't assign abc twice.

Following our exchange on the subject we will use the keyword val instead of const
