I think immutability of arguments should be optional by using a const keyword, like in c: int add(const int a, const int b);

  The downside to this syntactic approach is that the implementation details are leaked in the signature.

  I think it would better if they were immutable by default and instead of making them const, you would mark them mutable or reference.
