// I think this is possible, if we just ignore the names.
//
// year = :year, month = :month, day = :day
get("/date/:year/:month/:day") { (year, month, day) =>
    <ul>
      <li>Year: { year }</li>
      <li>Month: { month }</li>
      <li>Day: { day }</li>
    </ul>
}

// But if we ignore the names, bad things happen:
//
// year = :monht, month = :day, day = :year
get("/date/:month/:day/:year") { (year, month, day) =>
    <ul>
      <li>Year: { year }</li>
      <li>Month: { month }</li>
      <li>Day: { day }</li>
    </ul>
}

// Something like this might be able to put the parameters, 
// in any order, but it's not nearly as nice as what you proposed.
// 
// year = :1, month = :2, day = :3
get("/date/:2/:3/:1") { (year, month, day) =>
    <ul>
      <li>Year: { year }</li>
      <li>Month: { month }</li>
      <li>Day: { day }</li>
    </ul>
}

// Or, if it's just based on convention...
// 
// year = first :?, month = second :?, day = third :?
get("/date/:?/:?/:?") { (year, month, day) =>
    <ul>
      <li>Year: { year }</li>
      <li>Month: { month }</li>
      <li>Day: { day }</li>
    </ul>
}

Yes, this is definitely a feature that we would like to add. Thanks for the idea!
