I've got a short question about how Perl handles return values.

I've got a subroutine that returns multiple values, but in several cases I only need a subset of these values when calling the subroutine.

My question is: How can I specify which ones I want? Please have a look at this short example: 

my $result = get_values();

sub get_values {
    return (“a”, “b”, “c”);
}

In my testing $result always gets the value "c" (I assume because it's the last value). But is this guaranteed? Where is this documented? I didn't find anything at http://perldoc.perl.org/perlsub.html or http://perldoc.perl.org/functions/return.html and also perlmonks' search didn't help me out.

And taking this one step further: How can I get "a" and "c"? I know that I can just use three variables and ignore the second one, but I guess there's a better way to do that.

Thanks!
