> What I objected here is exposing false instead of nil when something is unset.
But there's no such thing in the PR linked to this item at all! That's what's
so frustrating to me here and why I've been urging you to look at what was
actually implemented for this ticket:
https://github.com/rpm-software-management/rpm/commit/67abf72ef57e58251271f5b218f867357d78a4e0
"opts" table always exists so you don't need to test *that* against nil each
and every time, and beyond that you get nil's for undefined options, and
strings for defined (empty vs non-empty depending on whether it takes an
argument or not). The other part is "arg" table (also always existing) where
you get leftover arguments as a native Lua sequence, accessible with arg[n] and
count with #arg.
Other improvements in this area are in the works and some already done, but
that's beyond the scope here.
