## Long story short Currently the documentation mentions `aiohttp.web.AbstractRouteDef` but `AbstractRouteDef` is not importable from aiohttp.web http://docs.aiohttp.org/en/stable/web_reference.html?highlight=AbstractRouteDef#aiohttp.web.AbstractRouteDef ## Expected behaviour `AbstractRouteDef` is importable from aiohttp.web or documentation mentions `aiohttp.web_routedef. AbstractRouteDef` ## Actual behaviour raise ImportError ## Steps to reproduce ``` >>> from aiohttp.web import AbstractRouteDef Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: cannot import name 'AbstractRouteDef' ``` ## Your environment aiohttp==3.3.2
