Yes, it has the same issue I describe.

Same.

Well, not an issue here. We don't ever want to write ugly,
error-prone code with the argument it'll run faster.
Which often it doesn't, either. Instead and more importantly
debug, devel, maintain and extend time, _our_ time, will grow
exponentially with every poorly written module we add.

actually much clearer to you, and everyone else.
