Decompiler Feature Request: re-sugar partially applied lambda expressions

```
Instead of,

<@ [1;2;3;] |> List.map (fun i -> i+1) @> |> source

producing

"[1; 2; 3] |> let mapping = fun i -> i + 1 in fun list -> List.map mapping list"

should produce

[1;2;3;] |> List.map (fun i -> i+1)

N.B. I consider this a high value but non-trivial feature.
```
