 There are no restrictions on an `appendInterpolation` method's argument list, generic parameters, availability, or error-throwing behavior.
 
-If `appendInterpolation` is overloaded, the Swift compiler will choose an appropriate overload using the labels and argument types of each interpolation. When choosing an overload, any accessible `appendInterpolation` instance method may be used, even if it does not meet all of the requirements above. However, if a `StringInterpolationProtocol` conformer doesn't have any `appendInterpolation` methods which meet all of the requirments, an error will be reported at compile time.
