我有以下功能:

func moveThing(thing: AnyObject, toLeft length: Int) {}
func moveThing(thing: AnyObject, toRight length: Int) {}

但是,当我将其中一个函数作为参数传递时,编译器会抱怨"不明确地使用'moveThing'"

func exec(function: (AnyObject, Int) -> ()) {}
exec(moveThing) // Apparently ambiguous
exec(moveThing as (AnyObject, toLeft: Int) -> ()) // Still ambiguous

我怎样才能解决歧义？
