If I can add my own two pence (Because dammit this isn't 'Murica

), if anyone remembers my script protection idea, well this sort of thing could provide the functionality for my idea, unlike before, any application could opt into the script protection. For example, if you want to prevent some bad guy from modifying your code whilst still allowing it to be viewed as per the GPL terms, you could simply include code like the following:
And you could just leave it blank to prevent a stack and its objects from having their code deleted/modified but still allowing it to be viewed, it would be a totally opt in sort of trick, any devs who didn't mind or didn't need it could just leave that kind of code out. But it depends on whether you guys are still thinking about this or not.
