I am looking at the issue from the caller's viewpoint. I have an iterator constructor and I want to use an existing function that requires a re-iterable.
OK. But how many functions require a re-iterable? It doesn't seem to me to be a common requirement. And if they did, how often would it be a problem to construct a list? I see your point, but I can't imagine it's a common need. But your experience may differ. Paul.
