F# forwarding of optional parameter

Question

Is it possible to forward optional parameters e.g:

type Type() =
    member this.A(?param) = printfn "%d" <| defaultArg param 0
    member this.B(?param) = this.A(param)  // how to do this ?

Answer 1

Like this:

    member this.B(?param) = this.A(?param = param)

Using ? when providing a named optional parameter allows you to pass an option.
