<div>You could probably get away with using a trailing ... in the call, as in<br></div>

<div>func foo(xs: [Int]...) {<br></div>
<div> bar(xs...)<br></div>

<div>I also wonder whether there's a reason Swift doesn't already support this. Maybe there's some desired future change to variadic arguments to improve performance (i.e. to avoid having to allocate an array) that wouldn't be compatible? Although I'm not sure what that would be. Maybe there's actually no barrier at all and it was just something that wasn't prioritized. It would be good to know either way.<br></div>
