The type parameters from the initial declaration are visible within an
extension, even without adding type parameters to the extension
declaration:
1> extension Dictionary {
2. func doSomething(e: Value) -> () {
3. // note that Value here is the same as Dictionary<Key, Value>
4. }
5. }
If you find this confusing, please file a Radar.
