Looking at the original issue, I think this may be too special-case-y; I believe this same thing can happen for structures that aren't classes (e.g. what if this were on an object method instead of a class method?)

You may also want to ensure this kind of fix handles the case where the class has comments attached to it.

I suspect we have the right logic somewhere else in another quick fix, though, especially for things like extract variable.
