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?
