The problem is 'no available video device' when trying to init
SDL. I've recently wiped/re-installed this machine so something
must be missing.
But I'm not sure if maybe I changed to much about it.
My point is, that I think it's generally a good idea to be
flexible when possible, and not make (im)mutability demands
unless actually necessary.
You may know the following, but I feel like there may be some
confusion about it: Note that

I've stepped through the debugger and I see the embedded
structure being set to 2, and dog.

That 'auto' is the problem. You want 'this.bottom = ...' instead.
