v_melnik has asked for the wisdom of the Perl Monks concerning the following question:

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!
