in reply to OK to always return a value?

You can return values from a subroutine invoked in a void context, but Perl shoves them into /dev/null, so be sure you perform regular maintenance on your machine to empty /dev/null.

    No prob, I have a crontab entry that already does this. 

    1 * * * *  perl -e "push(@b,glob) for @ARGV ;END{unlink $_ for @b}" /d
+ev/null/*

    Of course this misses subdirectories. I just do them manually.
