"Undoubtedly there are exx. in NT where, either alone or in conjunction with
another verb in the aorist, a verb in the perfect functions in a clearly
aoristic sense in the narrative; and often the perfect stem assumes aoristic
endings in the papyri and NT- a disguise which helped it to survive a little
longer:"
(now follows about 2 pages of examples in small print) cf. vol 3 of
Moulton's Grammar of the Greek New Testament, p. 69ff.
This seems sufficient "ground to stand on..."
