May I suggest to remove the second argument of spl_autoload() ?
spl_autoload() is typically called from the PHP core only, and the core
never sets this argument. File extensions to consider are set using
spl_autoload_extensions(). So, the 2nd argument of spl_autoload() is
useless and probably never used anywhere.
The problem with this argument is that it creates an annoying issue when
thinking about a way to extend autoloading to other symbol types (namely
functions and constants). The easiest way to extend autoloading to other
types is to add an optional second argument to autoloaders. For a
perfect BC, the core would call an autoloader for non-class symbols only
if the function accepts 2 arguments. This way, we can achieve full
backwards and forward compatibility with existing autoloaders. The
pre-requisite is that currently existing autoloaders take only one arg,
hence my suggestion to remove the second argument of spl_autoload()
(spl_autoload() will remain a class-only autoloader).

François
