Code on 2.048:

import std.stdio;

interface Timer
{
    final void run() { writeln("Timer.run()"); };
}

interface Application
{
    final void run() { writeln("Application.run()"); };
}

class TimedApp : Timer, Application
{
}

import std.stdio;

void main()
{
    auto app = new TimedApp;
    app.Timer.run();            // error, no Timer property
    app.Application.run();      // error, no Application property
    app.run();                  // This would call Timer.run() if the two calls
                                // above were commented out
}

The comments state what happens.

Note that if I changed the order of the TimedApp signature like so:

class TimedApp : Application, Timer

then the Application's run() method would be called instead of Timer's in the
app.run() call.
