Comment (by nthiery):
Oops, really, `reflections` does not return a collection of reflections?
It makes sense to index the reflections by roots; and it can be ok to have
the index set depend on the implementation, and or to return the
collection as a plain list/tuple. But returning a family of roots indexed
by reflections feels really weird. I am surprised I did not catch this
earlier.
@stumpc5: by default I would indeed wait for a strong use case before
adding a layer of complexity.
