I assume a function with attribute inference here, but it's the same without
inference. The point is: the language doesn't define `pure` to imply `scope` in
any way, neither is this expected behavior.

What about attribute inference becoming intractable like I mentioned?

I meant "mark it `pure` and *don't* add `scope` parameters". The point here is:
non-scope is the default, there's no need for a `nonscope` keyword or
workaround when you don't introduce a special case where `scope` becomes the
default.
