While I don't think that syntax is that important, I am fond of sugar.

Because I've been working in D for a while, here's how you'd do it in D.

    import core.time: Duration, dur;
    import std.datetime: Clock, SysTime;

    Duration days(int number) {
      return dur!"days"(number);
    }

    SysTime from_now(Duration duration) {
      return Clock.currTime + duration;
    }

    void main() {
      import std.stdio: writeln;
      writeln(2.days.from_now);
    }
