Subs are declared as part of the packge, not part of an object.
If your Object->new() method dynamically creates a sub called foo, then you're in effect declaring Object::foo. This sub is now bound to the package, and therefore will stick around until the end of the execution
There are several approaches:
## autoload
sub AUTOLOAD
{
my $self = shift;
( my $subname = $AUTOLOAD ) =~ s/.*:://;
if( $obj->{ $subname } ) {
## this is over simplified, so you may need to do
## other checks...
return $self->{ subname };
} else {
croak "No such sub";
} }
If you just want to get/set attributes, I recommend the AUTOLOAD way rather than dynamically declaring subs. There would be no residual subs floating around that way

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).
