FWIW: an even less stable hack would be to write something like an 'INIT {}' or 'CHECK{ }' block to indentify all defined packages/classes after compilation which inherit from the BASE_CLASS:: ( see ->isa in UNIVERSAL )

all those packages could then have a new AUTOLOAD added via eval.

this will not work in all cases because those timing issues in Perl are highly flexible:

• a sub could have been called before compilation finished.
• a class could be defined dynamically afterwards at runtime
• ...
