Hey jack,
As I said before, I think the design you have is wrong if your needing
to code in a hacky way such as this. The way you articulate the
justification for using shutdown almost certianly clarifies an
incorrect design.

Well, I am only a beginner myself but here are my 2 cents:

- As far as I know traits cannot be directly instantiated, only

You are using a dispatch snippet, which means the name after . in
