Subject: Re: Missing: List.map_some
Hi Ivan,
Thanks for the patch. Unfortunately, I'm no longer maintaining
missinglib since I no longer use OCaml (switched to Haskell). However,
the Debian OCaml Team is maintaining a branch of it, so you may want to
contact them at [EMAIL PROTECTED]

Could you add this function to missinglib?
In many of my ocaml programs, I end up writing this function (or
something equivalent):
(* Should be in List *)
let list_map_some f l =
let rec m n o =
match o with
[] -> n
| x::xs ->
(match f x with
Some v -> m (v::n) xs
| None -> m n xs )
in List.rev(m [] l)
The last time I wrote that function, I had a typo, which cost me a few
hours of debugging other code before I found what was going on.
Thanks,
Ivan
