I forgot to mention one thing: It need not be perfect! Far from it... :) Just a simple tool, to facilitate letting a script (Lua) control a Cocoa application. Therefore, I just might go for making a few quick implementations for common argument- and return type combinations, and use NSInvocation for everything else. Then the user can install their own quick handlers for combinations that aren't covered yet. But libffi seems like a very interesting option. Michael Ash mentions PyObjC and RubyCocoa, a quick check reveals that they both use libffi. Any further questions regarding this will be sendt on the objc mailing list. Thanks!
