API change in hook-adding

[xoft]

Now that you mention it, yes, it is possible to keep the old way, too. That would be the best way to do it. It'll be a bit more work to write it correctly, but it should work. The binding function will have to check parameter types, and if it detects old-style signature, it can provide the old behavior (with a warning to the console). Why didn't I think of it sooner?
