From skimming the module documentation it looks like you should be able to do this:

$some_package->super("some_method")->($obj, @arguments);

which would fill in all of the "walk the symbol table" bits in the second option that I gave you for how to solve this.

I wouldn't have noticed that if I hadn't read carefully with the expectation that chromatic was almost certainly right that it could indeed solve your problem.
