and ensure that the object looks like a script.  That means no args, no return, and no closure.
_PyCode_GetPureScriptXIData() takes it a step further and ensures there are no globals.

In the `ast` documentation for Python:

* https://docs.python.org/3/library/ast.html#ast.Dict
it is made clear that:

> When doing dictionary unpacking using dictionary literals the expression to be expanded goes in the values list, with a `None` at the corresponding position in `keys`.

Hence, `keys` is really a `expr?*` and *not* a `expr*`.
