Dear monks,

I saw a cool trick that XML::LibXML, Throwable and some other libraries can do: when you try to get the value of the variable containing a reference to the object, you get the result of calling one of its' methods (for example as_string() instead of "SomeClass=HASH(0xdeadbeef)".

How to do that?

Thank you!

UPD: Thank you for replies, the "overload" pragma is exactly what I need!

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