Hi Rowan, Thank you for confirming the nature of include, et. al. So, if the functionality to be notified via a callback for all symbols loaded is a desired feature by other than me and maybe Juliette then the best approach I've come up with is to add an spl_autoload_callback() function that can both get and set the callback to be called after include or its 3 other friends are called. Anyone (else?) disagree? -Mike
