I’ve actually got it rewritten to this:

let delimeters (value:string) = seq { for m in Regex.Matches(value, “\[([^]]*)\]”) do
yield m.Groups.Item(0).Value } |> Seq.to_array

But your version is even simpler. Cool!

———————————-
let delimeters (value:string) = Regex.Matches(value, “\[(.)\]“) |>
Seq.cast |>
Seq.map (fun (x:Match) -> x.Groups) |>
Seq.map (fun x -> x |> Seq.cast |> Seq.nth 1) |>
Seq.map (fun x -> x.Value) |>
Seq.to_array
——————————
When you can just write:

[| Regex.Matches(value, "\[(.)\]“).[0].Groups.[1].Value |]

Or did I miss something?
thanks
