I learned from this previous question about the semantics of memento(te) that memento(te) is not morphologically a future imperative. It turned to be a perfect imperative (semantically present), as it was formed from the perfect stem. I had previously thought of -to as a future imperative ending exclusively. I would like to know how unique memento(te) is in Latin.
Are there other examples of perfect imperatives than memento(te)? Or are there any other examples if imperatives ending in -to(te) than the usual future imperatives, perfect or not?
Such forms are not found in conjugation tables — or they have magically evaded my sight — but there might be some rare occurrences.
