Correct, but that's not enough to preserve BC. OK, giving a default value of 'class' to the second arg allows using a 'new-style' autoloader with an 'old-style' PHP engine. But, now consider the opposite, using a 'new-style' PHP engine, with autoloading extended to functions and constants, with one or more 'old-style' autoloaders: when the engine needs to autoload a function or a constant, we must not call any 'old-style' autoloader, as it would take the symbol and attempt to load a class by that name. And the easiest way to decide if an autoloader is a new or old-style one is to check if the autoload handler func is declared with one or two args.
