Theoretically, if you have an object implemented in Perl (e.g.), you can 
define it in such a way that any method call results in a lookup, the 
lookup being potentially arbitrary code such as asking a remote site, 
checking the results of a random number, etc. An object in pure Perl 
typically isn't explicitly labelled as being "an SVGMatrix", it just 
happens to act like one. Or doesn't. Or acts like one for a bit then stops 
acting like one half way through...
