Sort returns a SortedRange, so if you passed it to a function which could take
advantage of that (such as find), it would be more efficient to use the result of
sort, but sort sorts in place. So, if you want a new array, what you should
probably do is simply
auto temp = set.keys.dup;
sort(temp);
However, I think that .keys returns a newly allocated array such that you
don't need to dup it at all if you don't want to, which means that you'd do
something more like
auto temp = set.keys;
sort(temp);

This pretty much _is_ the forum for absolute beginners. The whole point of
this forum is to answer questions for those learning D. It's digitalmars.D
which is for general discussion on D. You're in the right place.
