send positional args (just for copy so far)
no, like this.  you get hashrefargs or you get arrayrefargs, not both
typo
ahh, we already have an arg opt field
other return codes

bug
named nexting
ok, I can read configs from start or from run
ugh, the positional args don't have values... must copy from $args I guess
