Motivation Motivation
========== ==========
Representing structured data using (potentially nested) dictionaries with string keys is a common pattern in Python programs. :pep:`589` allows these values to be type checked when the exact type is known up-front, but it is hard to write read-only code code that accepts more specific variants: for instance, where fields may be subtypes or restrict a union of possible types. This is an especially common issue when writing APIs for services, which may support a wide range of input structures, and typically do not need to modify their input.

For illustration, we will try to add type hints to a function ``movie_string``:: For illustration, we will try to add type hints to a function ``movie_string``::
