That restriction seems beyond the scope of the language definition.
Still, it can be trivially provided for.

Trivial, I should say.

Maybe. Point is, whether it's done this way or that is irrelevant from
the point of view of functional correctness. Whether an integer is an
object or not has absolutely nothing to do with the implementation of
And thus, Python variables are barely distinguishable from C variables.
