Dear monks,
I'm trying to understand how attributes work. I still don't get it. Why does the following not work (and is it fixable)?
package Attr;
sub new :Constructor { return bless {}, shift }
sub set_blah :Mutator {
my ( $self, $blah ) = @_;
$self->{blah} = $blah;
return $self;
}
sub get_blah :Accessor {
my $self = shift;
return $self->{blah};
}
1;
package main;
my $obj = Attr->new;
$obj->set_blah('I just set something!');
print $obj->get_blah;
All I get is Invalid CODE attribute: Constructor at /Users/rvosa/Desktop/Attr.pl line 3. So is it possible to set (arbitrary) attributes on methods, and how is that done?

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
