InlineEnum & InlineDU

[Xyncgas]

Maybe

type [<Struct>] myRecord =
    {
        Picture : | JPEG = 0uy | PNG = 1uy
        State : | Enabled | Disabled | Empty
    }

And

let myFunction (arg1) (arg2) =
    match arg1 with
    | (myInlineEnum = 1uy) as e -> () //inline enums
    | _ -> ()
    match arg2 with
    | (myInlineDU) -> ()
    | _ -> ()

arg1 infers to anonymous enum that contains myInlineEnum = 1uy, arg2 infers to anonymous discriminative record that contains a case called myInlineDU
