But consider this. It's only an impure function which might alias
a global. And since you already have access to the global in the
impure function, there might be less incentive in general to pass
it through a function. Other than that, you're stuck with a
theoretical "@impure!varName" function attribute, for example,
which tells the caller which globals are accessed.
