F# explicit match vs function syntax

Question

Sorry about the vague title, but part of this question is what these two syntax styles are called:

let foo1 x = 
    match x with
    | 1 -> \"one\"
    |         


        

Answer 1

The pro for the second syntax is that when used in a lambda, it could be a bit more terse and readable.

List.map (fun x -> match x with | 1 -> "one" | _ -> "not one") [0;1;2;3;1]

vs

List.map (function 1 -> "one" | _ -> "not one") [0;1;2;3;1]
