Why isn't it sufficient to enhance test-op to take a :config-file
argument, and pass it through using operate?  I.e., can't you get what
you need with something like

(asdf:oos 'asdf:garys-test-op garys-system :test-config
"/home/gwk/my-config-file")

?

I forget the actual details (I'm not conveniently located), but wouldn't
that make an instance of garys-test-op with a binding for a test-config
slot that you could examine in your perform?


Best,
Robert
