Re: [Ocaml-lib-devel] ExtArray?

[Jonathan R. <jon...@gm...>]

IMO, Array.filter should return an array of the same size. Reason:
whilst arrays are mutable, they are not resizable.

Then it's just a specialised Array.map.

let filter pred =3D map (fun elt -> if pred elt then Some elt else None);;

find_all then builds a list by unwrapping all values Some 'a from filter.

My 2c,
