Do you mean something like this? It's handy:


enum Options {
    Some, Many, All
}

class OptionManager(Options opt) {
    static final switch(opt) {
        case Options.Some:
            alias TypeTuple!(int) TP;
            break;
        case Options.Many:
            alias TypeTuple!(int, int, int) TP;
            break;
        case Options.All:
            alias TypeTuple!(int, int, int, int, int, int) TP;
            break;
    }

    public this(TP params) {
        // ...
    }
}
