Hi,
Is there any way to make a variable single-assignment, regardless of its
type? I.e.:
void foo()
{
<some magical keyword?> int i = 0;
i = 2; // Error: i cannot be reassigned
}
I realize const and immutable will do this, but they are transitive and
infect the type, which I do *not* want. I simply want the variable to be
single-assignment. Is it possible?

You can create a struct Final you could use as Final!(type) variable;
Overloading opAssign should do whatever you need.
I don't think adding to the core language what could ba achived with a
nice abstraction should be done.
