Should default values be prohibited here?

infix operator **

func **(num: Double = 1, n: Double = 2) -> Double {
    pow(num, n)
}

or should they work? Straw man syntax:

123.4 ** default

let x = (**)(5)

That is weird. :roll_eyes: I didn't think it was possible to cast a function with defaults to a closure that leaves off any arguments. E.g.

(**) as (_, _) -> _ // compiles
(**) as (_) -> _ // doesn't

Any idea why it works here?

And how about getting the default for the first argument, rather than the second? Impossible?
