$object_instance -> set_state ( "here is a new state" );
is translated by perl (because it knows it's a 'MyObject' because of that 'bless') into:
MyObject::set_state ( $object_instance, "here is a new state" );
This is actually not quite true. "set_state" could be implemented in a base-class and in the general case that base-class might not be known at compile-time, so Perl cannot do any "translations" but actually has to perform a search for the proper method in the parent-class hierarchie at run-time.
At least that is my understanding...

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).
