When final switch supports structs, writing a fizzBuzz
(http://imranontech.com/2007/01/24/using-fizzbuzz-to-find-developers-who-grok-coding/
) gets simpler and safer:


import std.stdio, std.typecons;
void main() {
    foreach (immutable i; 1 .. 101) {
        final switch (tuple(i % 3 == 0, i % 5 == 0)) {
            case tuple(false, false): writeln(num);        break;
            case tuple(false,  true): writeln("Buzz");     break;
            case tuple( true, false): writeln("Fizz");     break;
            case tuple( true,  true): writeln("FizzBuzz"); break;
        }
    }
}
