So, I noticed that [this question](https://stackoverflow.com/questions/16630087/r-why-is-the-approach-for-subsetting-a-list-faster-than-using) mentions one person's experience with `[[` being faster than `$` for list-element extraction, however I was wondering if anyone has a definite answer as of R version >= 3.0.2? 

A colleague of mine has seen situations were `$` is faster, yet this was sometime ago (and with Rcpp), and I'm wondering if anything has changed with R's evolution...
