[Catalyst] Catalyst::Plugin::FormValidator --> What does the ' prepare' method really do and is it necessary?

[kakimoto at tpg.com.au]

hi, guys,
 Was looking through Catalyst::Plugin::FormValidator's source code.

Was wondering what does the ' prepare' method really do and is it necessary?
I mean looking at the code, what's the significance of     "$c =
$c->NEXT::prepare(@_);".
Was wondering if i could just use ->form straight away and cut the
complexity.

Extract 1: 'Prepare' method source code
==========================

=head3 prepare

Sets up $c->{form}
=cut

sub prepare {
    my $c = shift;
    $c = $c->NEXT::prepare(@_);
    $c->{form} = Data::FormValidator->check( $c->request->parameters, {} );
    return $c;
}


thanks
