1) I will not mutate data through this reference. For example,
a parameter that is pointer to const achieves that:

2) This variable is const:
const i = 42;
Well, there is the confusion: There is no "reference" in the
second case at all!
I think this second case should not be allowed. Use
immutable i = 42;
instead. The meaning is identical, but we could remove the burden
of two different meanings from const if it is not allowed. const
should only be allowed in function declarations. A variable must
be declared either mutable or immutable. It's only functions that
may guarantee not to modify a parameter or the objects they
belong to, and so are allowed to work on both mutable and
immutable objects.
