@VisualMelon no, you cannot but you can prevent enumerating the source that you are going to reverse until really necessary. The first implementation doesn't do it and the stack pulls all the items from the source right away. You can check it in linqpad with var reversed = source.Select(x => x.Dump()).Reverse(); - the first one will dump all the items and the second one not.

Max implementation is a great example. @t3chb0t you can't lazily reverse a lazy IEnumerable ;) you'd have to fast-path IReadonlyList and such to achieve that (where it's possible)

| Aug 11, 2018 at 14:48 | comment | added | t3chb0t | This is a nice trick with the stack... I think you could just return it without the helper variable. Althogh it has one drawback. It's eager whereas linq is lazy so this API isn't consitant with the others. | |
