After changing your parentheses to curlies in your sub, and adding a,b,c variables, then assigning the output of your sub to a scalar variable (a reference), I just print the results using Data::Dumper. I also print what is returned by the ref function: 
use strict;
use warnings;
use Data::Dumper;

my $ref = parse();
print Dumper($ref);
print ref $ref, "\n";

sub parse {
    my @a = 0..2;
    my %b = (foo => 7);
    my $c = 55;
    return {
       a => \@a,
       b => \%b,
       c => $c
    }
}

__END__

$VAR1 = {
          'c' => 55,
          'a' => [
                   0,
                   1,
                   2
                 ],
          'b' => {
                   'foo' => 7
                 }
        };
