Yep. This is explicitly what I listed as "as long as you don't (a), evaluating at runtime". This extremely specific and rare case is outside of the scope of "Generally, this works". It means that some, very few definitions still need to be in old style, but the majority of your code is fine.
I didn't say you couldn't make it work by writing it differently. The point was obscure errors can pop up, which is a drawback to the way they chose to do things. That holds.
