in thread wantarray alternative

I did not intend to ask the question How do I use the tertiary operator?. Both these answers rely on the trivial lc operation I used in my example.

To rephrase: What's the most elegant way to modify the default behavior of a subroutine that returns a list of one?

sub lowercase { my @out = map { lc } @_ ; return wantarray ? map { $_ } @out : first { $_ } @out ; }

So my specific question is: How can I move the operation from the first line into the second line to avoid using the place holder out?
