When is a Client a Client?

[Kevin Moore]

// oauth.dart

import 'package:http/http.dart'

Future authenticate(Client cleant) { ... }

We could imagine that io_client.dart, besides providing an implementation of Client also provides IoClient extends Client with io-specific features.

// my vm code

import 'package:http/io_client.dart';

import 'oauth.dart';

void main() {
  var client = new IoClient(cookieStore: 'cookies.cks');
  authenticate(client); // is this a type warning?  
}

The Client in io_client.dart has no relationship to Client in http.dart – at least not in the URI rules we think of in Dart today.

I think we can address this with something like the proposal in #5 – The external library should effectively export the types from the canonical library.
