To add this thing would be a very major change and will open galactic-size can of worms (think "implicit conversions", "converting constructors", "multiple inheritance", etc.). And this would seriously complicate function call logic - which is very bad, because, unlike statically-typed language, we can not offload this complexity to one-time compile stage.

By your argument. Type hints check if the argument passed to function is of the right type. They don't make PHP call different functions on different argument types.

Assembly code is entirely irrelevant to the discussion, since, as I already explained once, difference between assebmly code and higher-level programming languages in in complexity incapsulation, while difference between operator overloading and using method is purely syntactical - operator overloading can be translated one-to-one to method calls without exposing any complexity, while translating method call to assemly exposes a lot of complexity. -- Stanislav Malyshev, Zend Products Engineer [EMAIL PROTECTED] http://www.zend.com/ +972-3-6139665 ext.115 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
