Updated excuse:
because all the way back outside in _parse, we know that:
1. expr is a dict (because of get_expr(False))
2. expr['pragma'] is also a dict, because we explicitly check it there.
3. We iterate over the keys; all we know so far is that the values are
... something.
4. _pragma()'s job is to validate the type(s) anyway.
More or less, the _ExprValue type union isn't remembered here -- even
though it was once upon a time something returned by get_expr, it
happened in a nested call that is now opaque to mypy in this context.
So, it's some combination of "That's all we know about it" and "It
happens to be exactly sufficient for this function to operate."
