Wow, I never knew it is a keyword, thank you!

I feel guilty for omitting in knowingly but we've been hearing that it would be deprecated. I don't think it will ever happen. :-/

Besides, I think retro(), its alternative, is not suitable for recursive algorithms because retro() works only with ranges.

I had once tried to do recursive iteration with ranges (probably on a tree) but it had turned out that iteration with opApplyReverse was more natural for recursion. (I may be wrong on my conclusion but that is what I remember now.)
