How would I go about reading the last 10 lines in a files? Or more generally, how do I go about collecting the last N elements of anything?
I'm looking for advice on the "right way" to do this using iterate.
On way would be to write collect-tail that just kept the last N elements:
(iter (for line :in-file my-file :using #'read-line) (collect-tail line :how-many 10))
Is this a good way?
