Try this:

sub total{ my $sum = shift(@_); foreach (@_){ $sum += $_; } return $sum; }
  • add $_, not @_
  • return $sum
  • Add trailing } to match braces

    Awesome! Fixed the problem--thanks much! I didn't know if Perl associated the default $_ while moving through the indices of @_.

      The mechanism of action is the foreach loop. It's just as happy aliasing $_ to elements of @this, @that, and @the_other as well. In this regard, @_ isn't special; foreach is.
