Syntax errors in my Perl (sorry, the last time I did Perl seriously,
we used an extension for named arguments)
sub new { my $class = shift; my $self = shift; bless $self, $class;
return $self; }
sub plus { my ($self, $arg) = @_; return $self + $arg; }
sub minus { my ($self, $arg) = @_; return $self - $arg; }
