Hi, I'm having trouble using SUPER to call an ancestor's constructor.
Say i've got an abstract class, Word, and a subclass, Noun, which derives from it, and calls it's parent's constructor, but then takes a few extra parameters.
The only way I can get it to work is to create and bless my $self and then call SUPER:
#!/usr/bin/perl -w
use strict;
package Word;
sub new
{ my $classname = shift;
my $self = {};
$self->{stem} = shift;
$self->{english} = shift;
bless $self, $classname;
return $self;
}
package Noun;
our @ISA = "Word";
sub new
{ my $classname = shift;
my $self = {};
bless $self, $classname;
$self = $self->SUPER::new(shift, shift);
$self->{gender} = shift;
$self->{nom_sg} = shift;
$self->{gen_sg} = shift;
return $self;
}
package main;
my $w = new Noun("ai(=m-", "blood", "n", "a", "atos");
print $w->{english};
This seems very clunky & makes me think it's hardly worth setting up the inheritance. But I know that in Java you can do it in one line, so I bet you can in Perl too?
Can anyone suggest an optimised version of the above?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
