> Tidy features (like pipes) are detrimental to performance.

But they are some absolutely amazing features to use. After helping my wife learn R, and learning about all the dypler features, going back to other languages sucked. C#'s LINQ is about as close as I can get to dypler like features in a main stream language.

Of course R's data tables and data frames are what enable dypler to do its magic, but wow what magic it is.
