can sortedbyit support optional "reversed" arguement?
currently, if I only knew the 2-steps method:
var people3 =people1.sortedByIt(it.name)
var people4 = people3.reversed()
echo people4
I don't konw whether the above implementation is high effiency. what if an
inner way like this
var people4 =people1.sortedByIt(it.name, True)
echo people4
