The problem is that the first time we go through the loop, when parm_idx

near the beginning of the loop is true
The parm shouldn't be a parameter pack in that case; the ... is part
of the default argument, not the parameter.
Yes, I see that. Then it seems to me that we have to catch the problem
(much) earlier...
Thanks,
Paolo.
