Original Text

I'm using this via Dist-Zilla-Plugin-UnusedVarsTests. Which complains
about an unused my $_; however $_ is not unused it's just that all
instances of it in the subroutine are implied.

sub something {
    my $_;
    my @array = ...;
    while ( @array ) {
        say;
    }
}

UnusedVarsTests would fail in this case even though technically $_ is
being used on say.

Follow-Up Report

oh some further discussion I had on StackOverflow
