Don't get confused between 'thunking' and mere indirect jumping/calling. A
thunk is where a direct jump/call vector is replaced at runtime (and is
thus a one-time thing per execution). I think what you are suggesting is
just passing in jump/call vectors, which would be jumped/called to by an
indirect jump/call instruction. The vectors could change (by being passed
in as hidden parameters) for each instantiation.
Nick.
