-Function annotations
-====================
-
-Function annotations are a piece of syntax introduced in Python 3.0 that was
-not backported to Python 2.x. (See PEP 3107:
-http://www.python.org/dev/peps/pep-3107/). They cause Python 2 to raise a
-SyntaxError.
-
-To rewrite Python 3 code with function annotations to be compatible with both
-Python 3 and Python 2, you can replace the annotation syntax with a dictionary
-called ``__annotations__`` as an attribute on your functions. For example, code
-such as this::
-
- def _parse(self, filename: str, dir='.') -> list:
- pass
-
-can be re-expressed like this::
-
- def _parse(self, filename, dir='.'):
- pass
- _parse.__annotations__ = {'filename': str, 'return': list}
-
-As described in PEP 3107, the annotation for a function's return value
-corresponds to the ``'return'`` key in the dictionary.
-
-(Note that PEP 3107 describes annotations as belonging to a
-``func_annotations`` attribute. This attribute was renamed in Python 3.2 to
-``__annotations__``.)
-
-Be aware that some libraries that consume function annotations, such as
-`Reticulated <https://github.com/mvitousek/reticulated>`_, have their own
-semantics for supporting earlier Python versions, such as decorators. If you
-are using such a library, please use its own mechanism for providing
-compatibility with earlier Python versions, rather than the generic equivalent
-above.
