What do you mean by that? Every element in the original iterable ends up in one of the groups; nothing is discarded.

I use this all the time. (Well, I often end up writing a "pairs" iterator by hand, and don't reach for grouper unless I already need it for different sized groups... But that's probably an argument _for_ putting it in the module, not against.)
