Hello,

I am just getting started with F#, and I am enjoying it. It seems like it's a common idiom to pipeline operations using |>. But what about making pipelining convenient when the input is an option? Specifically, if the input is None, then just return None, otherwise, apply the function and wrap it in a Some -- or don't wrap it if the function already returns an option. Something like these operations:

1
2
3
4
5
6
7
8
9
10
11

/// Like |>, except returns None if given None
let (|?>) a f =
   match a with
   | None -> None
   | Some v -> Some (f v)
 
/// Like |?>, but for use when f already returns an option
let (|?>>) a f =
   match a with
   | None -> None
   | Some v -> (f v)

Despite just starting, I have found these combiners to be already useful.

So I am wondering, are there pipeliners like these already defined? Do you think they're good style?
