rje,
As others have pointed out, there are already modules that do this. As revdiablo pointed out, there are ways to avoid using eval to dynamically create subs and this fully functional example allows them to be lvaluable.
package Cool;
use strict;
use warnings;
sub new {
my $class = shift;
my $self = bless {}, $class;
$self->_Init( @_ );
return $self;
}
sub _Init {
my $self = shift;
{
no strict 'refs';
for my $method ( @_ ) {
*{ $method } = sub :lvalue { $_[0]->{$method} };
}
}
}
"That's cool man";
And here is a script that uses it:
#!/usr/bin/perl
use strict;
use warnings;
use Cool;
my $obj = Cool->new( qw(foo bar baz) );
$obj->bar = "A better way of doing this";
print $obj->bar, "\n";

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).

or How to display code and escape characters
are good places to start.
