We had a miscommunication. Your answer tells me what that pcase
clause recognizes, but the question I am asking is a different one.
My question is about what values of RES are_valid_ at that point in
the code.
(anything else would be a bug in the code producing res).
My question is about the code producing RES.
What are the values it can produce, and what do they mean?
