It's also incorrect if you care about nils or order. Ipairs is
incorrect if
the arguments can contain nils.
Of course you're right. Those damn nils again.
The set of cases where nils matter when iterating over varargs is
probably
small, but it is potentially an issue.
Agreed. That makes me want apairs in the standard base library.
