to a Set
also removes duplicate values:
// This Vector contains repetitions of 'red' and 'blue'
$v = Vector {'red', 'green', 'red', 'blue', 'red', 'yellow', 'blue'};
$set = $v->toSet();
var_dump($set is \HH\Set<_>);
var_dump($set);
bool(true)
object(HH\Set)#2 (4) {
string(3) "red"
string(5) "green"
string(4) "blue"
string(6) "yellow"
}
