I think you misunderstand an infinite range. There are plenty

An example infinite range:

void popFront() {}
enum empty = false;
}
length has nothing to do with infinite ranges. In fact,
infinite ranges should have no length member.

Oh, I see. So they're truly infinite, not just unbounded.
In that case, how do you make a random-access wrapper around an
input range?
(i.e. What do you use for 'length'?)
