I like this idea.

Is there any rule/praxis for or against setting $@ inside my modules or subroutines -- as a way of returning error messages?

If using above example as a guide, would the following module be considered to be "kosher" perl? 

package Phone;
sub prettify {
    local ($_) = @_;
    return eval {
        /^$/ and die "No number\n";
        # do something to modify $_ here
        $_;
    };
}

In my main program this could then be called using: 

my $pretty_number = Phone::prettify($number)
if (not defined($pretty_number)) {
    # e.g. insert message $@ into web page output
}
