Java uses multi-method dispatch to work around missing default values:
function foo($a, $some_flag) { ... }
function foo($a) { foo($a, false); }
instead of
function foo($a, $some_flag = false) { ... }

Whatever example I'd give you'd probably say it's not the relevant one. 
But if you give me a use case for dynamic dispatch I show you how I'd do 
it in PHP. Maybe we should take that off list though and present just 
the result of our research :-)
