return(); (Score:1)
return()with no arguments (which is what you're doing) does the "right thing" in both scalar and list contexts. It returns either an empty list or undefined value.Thus you could also have written:
return;for the same effect. I'm sure you know this already, but from your commentary and style it did look like you were trying to explicitly return an empty list.

For less trickery with subs and call stacks and line numbers, remember your old friend 'do'!
$ perl -le'print join " ", (1, do { warn 2; () }, 3)'
2 at -e line 1.
