Question

[<Flags>]
type LikeMatch =
    | None  = 0
    | Start = 1
    | End   = 2
    | All   = Start ||| End //ERROR: Unexpected identifier in union case

I’ve also tried qualifying the members with the enum type. Is there a way to do this in F#?

Answer 1

According to the F# language reference there is no way to do this. The right hand side of the = sign in a F# enum must be an integer literal
