And with List::Util::reduce()... 

use List::Util qw/ reduce /;
sub min_max_avg {
  $res= reduce {
     my $r= ref $a ? $a : [($a) x 3];
     if ($b < $r->[0]) {
        $r->[0]= $b;
     } elsif ($b > $r->[1]) {
        $r->[1]= $b;
     }
     $r->[2]+=$b;
     $r
  } @_;

  return @$res[0,1], $res->[2] / @_;
}
