[Ocaml-lib-devel] No takewhile and dropwhile functions yet

[Richard J. <ri...@an...>]

I don't know whether I'm using an old version of extlib, but my
version doesn't include these vital functions:

let rec takewhile f =3D function
    [] -> []
  | x :: xs when f x -> x :: takewhile f xs
  | _ -> []

let rec dropwhile f =3D function
    [] -> []
  | x :: xs when f x -> dropwhile f xs
  | xs -> xs
