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);
