The future perfect active is usually formed periphrastically (unlike the m/p), but is there a future perfect active optative? To form it, you would need to add the perfect participle to the future optative of "to be." Mastronarde says on p. 320, "The future perfect active indicative (or opt.) is normally formed periphrastically, from perfect active participle plus future indicative (or opt.) of eimi."
Is this right?? Is this possible?? Can somebody point me to this future optative form of eimi??
Thanks in advance.
