Re: Overriding libraries

You can't override Input.php in a module because of the way that we start
up the system.  We specify certain modules that we know we're going to load
in application/config/config.php in the $config['modules'] setting.  Kohana
loads those modules, then does its bootstrapping which loads Input - at
that time it looks for overrides across all modules.  Later on, we look in
the db to see which modules you have activated and load those up as well.
 Net of all this is that your module is loaded too late to overload that
particular class.  :-/

As the system is currently, you can't have two MY_xxx overrides.  It'll
find one and use it.  We could wire up a second level of overrides without
too much difficulty but we'd have to decide on a nomenclature that makes
sense and it'd be an API change (backwards compatible, but older versions
wouldn't be able to use it).

You could try overriding xss_clean in MY_Input.php and have it get a module
var to see whether or not it should do the cleaning - then you can set that
module var elsewhere...
