I have code that could be adapted for this purpose. It is designed to add automatic type checking for methods and to allow optimizations to be turned off. I don't think it would be too hard to adapt it to changing optimization settings.
Here is the code. I could work on adapting it if no one else is interested. Let me know.

I'd be more than happy to be able to help with something like this. Should be able to find spare time to put something together by <pause> I dunno, next week.
