Calling a global function which has the same name as a member function

The `Array` type in Swift has a member function called `sort`, with its signature being `sort(isOrderedBefore: (T, T) -> Bool)`. This function differs from the global version of `sort`, which has the signature `sort(array: T[], pred: (T, T) -> Bool)`. If one extends an `Array` (see Why does the same method fail when inside an Array extension in Swift?), calling `sort` from inside the scope of the `Array` extension will naturally result in the local version being used. Is it possible to explicitly call a function from an outer scope, or specifically from the global scope, even if its name coincides with that of a function from an inner scope? This would be similar to the C++ scoping resolution operator, `::`
