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? - Alex
In D1 you could use final, in D2 your choices are either const, immutable, or as others have suggested, some sort of a wrapper. You could also use enum if you only want to work with primitive types and the value can be calculated at compile time.
