I have a Set data structure which has no concept of order; its members are stored and can be searched efficiently based on their hash.
I have a situation where chain()'ing them together would be convenient, but InputRange requires front() and popFront(). There really isn't a front, and creating a new Set with an element removed would be unpleasant.
What would be the best way to iterate across a list of such Set's? For now I'm just going to write the explicit loop.
Thanks!
