For an equation of the form <code>X ≡<sub>A</sub> Y</code>,
where <code>X</code> and <code>Y</code> are types involved
in an assignment (including parameter passing and return statements),
the top-level type structures may unify loosely but element types
must unify exactly, matching the rules for assignments.

   * Returns an unmodifiable iterable over the nodes in a tree structure, using pre-order traversal.

[TestFS] now returns a structured error that can be unwrapped
(via method `Unwrap() []error`). This allows inspecting errors

        TensorList operations.
    *   `tf.custom_gradient` can now be applied to functions that accept nested
        structures of `tensors` as inputs (instead of just a list of tensors).
        Note that Python structures such as tuples and lists now won't be
        treated as tensors, so if you still want them to be treated that way,
        you need to wrap them with `tf.convert_to_tensor`.

## An example file structure

Let's say you have a file structure like this:

```
.
