This function is available as Vec\sort() in Facebook's www repository.

Returns a new vec sorted by the values of the given Traversable

namespace HH\Lib\Vec;

function sort<Tv>(
  Traversable<Tv> $traversable,
  ?(function(Tv, Tv): int) $comparator = NULL,
): vec<Tv>;

If the optional comparator function isn't provided, the values will be sorted in ascending order.

To sort by some computable property of each value, see Vec\sort_by().

Time complexity: O((n log n) * c), where c is the complexity of the comparator function (which is O(1) if not provided explicitly) Space complexity: O(n)
