Another thought: If `@_` is not generated, how do modules like
Carp::Always inspect the args of all of the callstack? Currently those
look at (I believe) @DB::args though the exact logic confuses me. Will
that remain working here?
$ perl -MCarp::Always -E 'sub A { B(123); } sub B { C(456); } sub C {
die 789; } A' 789 at -e line 1.
main::C(456) called at -e line 1
main::B(123) called at -e line 1
main::A() called at -e line 1

I think it's implemented by:
