    ( impl < { O: .., I: 'static, $( $bound:tt )* }> EnsureOriginWithArg<O, $t_param:ty> for $name:ty {} ) => { ... };
    ( impl < { O: .. , $( $bound:tt )* }> EnsureOriginWithArg<O, $t_param:ty> for $name:ty {} ) => { ... };

}

Simple macro to explicitly implement EnsureOriginWithArg to be used on any type which implements EnsureOrigin. This is quick and dirty, so you must use the type parameters O (the origin type), T (the argument type) and AccountId (if you are using the O: .. form).

The argument is ignored, much like in AsEnsureOriginWithArg.
