That got me thinking of how mocking frameworks make it easy to 
pass in dependencies without having to write a whole new "test 
double" type oneself. How would one do that for what I've 
started calling "static interfaces"? How would one mock an 
input range?

I have a mocking framework here:

Maybe that is useful? The only problem with mine is that it needs 
to be injected inside an interface. Like this:

interface InputRange(T) {
    @property T front();
    void popFront();
    @property bool empty();

    mixin Mockable!(InputRange!(T));
}

auto mock = InputRange.getMock()
