Answer 1

you mean something like this ?

open System

type SomeLogger() = 
    member this.Error(format : string, []args : obj[] ) = ()
    member this.Info(format : string, []args : obj[] ) = ()


module Extensions = 
    type SomeLogger with
        member this.FInfo format = Printf.ksprintf (this.Info) format
        member this.FError format = Printf.ksprintf (this.Error) format

open Extensions

let l = new SomeLogger()
l.FInfo "%d%s" 10 "123"
