That's the new version, right? and I made that "fix" when I created the new method because the old code actually called the initializers with that type of object, which meant that if you violated the rule, you could actually have a bug. It's one of those subtle "this is why the compiler is failing" things.

That seems wrong, so I probably got the capture wrong. I was planning to go in and deal with the remaining uses of the deprecated method, and since I now have bigger fish to fry I would leave it and I'll deal with it later. The new thing is a new API and means we can change it to whatever we want, and it won't be in the 3.3.1 patch.
