The steps from the root of a tree to one leaf; callable on the tree.

    >>> from clika_runtime import pytree
    >>> tree = {"layer": [10, 20]}
    >>> acc = pytree.tree_accessors(tree)[1]
    >>> acc.codify()
    "*['layer'][1]"
    >>> acc(tree)
    20
    >>> acc.path
    ('layer', 1)
    

## `entries` (property)

The typed steps, root to leaf.

## `path` (property)
