Review comment:
That's right. Because this is a decorator, the function's type is that
which takes a function and returns another function.
I.e. ptransform_fn's `fn` argument is a Callable, and the result of calling
`ptransform_fn` is another callable that returns a `_PTransformFnPTransform`.
```
type: (Callable) -> (...) -> _PTransformFnPTransform
^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
param fn return type
```
