I had a problem with the previous sub (when calling it in scalar context and not passing a reference). I was able to get the following to work: 
sub name {

    #%% reference argument if it is not a reference
    my $string = ref $_[0] ? $_[0] : \$_[0];

    # processing    

    #%% use return caveat
    $$string;
}
