It is a hassle. I recently changed my ORM's API from returning iterators
to lists based on similar user feedback (and I could have sworn I
already made this comment on this issue, but I can't find it now). That
experience hints to me that any interface that prefers iterators over
lists is going to be resisted; builtins doubly so.
