Comments on first function

Hi, Alexandru. If you just need more performance on vectors only, there are the core functions mapv, filterv, and subvec (O(1), which can be used to implement takev and dropv). Also, looking at the source of mapv and filterv is instructive, because they use transients internally; you might do
