And keep in mind, too, even though those high-order functions take the 
delegate/closure as a template paramater, you CAN still rig it up for the 
delegate/closure to be changed at runtime (as long as the delegate's 
signature is the same):

auto myDelegate = (Car c) => c.getPrice;

// Change it at runtime:
if(foo)
    myDelegate = (Car c) => c.getPrice + 7;

auto carPrices = map!myDelegate(list_of_cars);
