Save retron function as non-throwing closure

As I understand it, rethrows

it essentially creates two functions from one declaration / definition, e.g .:

func f(_ c: () throws -> Void) rethrows { try c()}

// has the same effect as declaring two seperate functions, with the same name:

func g(_ c: () throws -> Void) throws { try c() }
func g(_ c: () -> Void) { c() }

      

        
        
        
      

    

If I have a rethrowing function, for example f

, is there a way to store it as a no-throw form closing in it? Hypothetically, like this:

let x: (() -> Void) -> Void = f
// invalid conversion from throwing function of type '(() throws -> Void) throws -> ()' to non-throwing function type '(() -> Void) -> Void'

x{ print("test") } // "try" not necessary, because x can't throw
